# Is Postman Down? Complete Status Check Guide + Quick Fixes

*Originally published on [API Status Check](https://apistatuscheck.com)*


**Postman stuck on "Sending request..."?**  
**Collections not syncing?**  
**API calls timing out?**

Before assuming Postman is down, verify if it's actually a service outage—or a problem with your setup. Here's your complete guide to checking Postman status and fixing common issues fast.

## Quick Check: Is Postman Actually Down?

**Don't assume it's Postman.** 70% of "Postman down" reports are actually local network issues, workspace sync problems, or API endpoint failures—not Postman itself.

### 1. Check Official Sources

**Postman Status Page:**  
🔗 [status.postman.com](https://status.postman.com/)

**What to look for:**
- ✅ "All Systems Operational" = Postman is fine
- ⚠️ "Partial Service Disruption" = Some services affected
- 🔴 "Service Disruption" = Postman is down

**Real-time updates:**
- Postman API status
- Workspace sync issues
- Postman Monitors status
- Mock Server availability
- Collection Runner problems
- Postman Flows status
- Regional outages


**API Status Check:**  
🔗 [apistatuscheck.com/api/postman](https://apistatuscheck.com/api/postman)

**Why use it:**
- Real-time monitoring (checks every 5 minutes)
- Historical uptime data
- Instant alerts (Slack, Discord, email)
- Tracks API, Monitors, and Mock Servers separately


**Twitter/X Search:**  
🔗 Search ["Postman down"](https://twitter.com/search?q=postman%20down) on Twitter

**Why it works:**
- Developers report outages instantly
- See if others experiencing same issue
- Postman support team responds here

**Pro tip:** If 200+ tweets in the last hour mention "Postman down," it's probably actually down.


### 2. Check Service-Specific Status

**Postman has multiple services that can fail independently:**

| Service | What It Does | Status Check |
|---------|--------------|--------------|
| **Postman API** | Core API platform | [status.postman.com](https://status.postman.com/) |
| **Workspace Sync** | Team collaboration & sync | Check status page under "Sync" |
| **Monitors** | Scheduled collection runs | Check status page under "Monitors" |
| **Mock Servers** | Mock API responses | Check status page under "Mock Servers" |
| **Postman Flows** | Visual API workflows | Check status page under "Flows" |
| **Collection Runner** | Automated testing | Check status page under "Runner" |
| **Postman Interceptor** | Browser request capture | Chrome extension status |

**Your service might be down while Postman globally is up.**

**How to check which service is affected:**
1. Visit [status.postman.com](https://status.postman.com/)
2. Look for specific service status
3. Check "Incident History" for recent issues
4. Subscribe to status updates (email/webhook)


### 3. Test Different Postman Platforms

**If Postman web works but desktop app doesn't, it's likely your app/network.**

| Platform | Test Method |
|----------|-------------|
| **Desktop App** | Launch Postman, try simple GET request |
| **Web** | [web.postman.co](https://web.postman.co) |
| **VS Code Extension** | Try Postman extension in VS Code |
| **CLI (Newman)** | Run collection via Newman CLI |

**Decision tree:**
```
Web works + Desktop fails → App/sync issue
Web fails + Desktop fails → Postman service down
Newman works + Desktop/Web fail → Workspace sync problem
Nothing works → Postman is down (or firewall blocking)
```


## Common Postman Error Messages (And What They Mean)

### Error: "Could not get any response"

**What it means:** Postman can't reach the API endpoint.

**Causes:**
- API endpoint is down (not Postman)
- Network firewall blocking requests
- Proxy/VPN interference
- SSL certificate issues
- CORS errors (web version)
- Request timeout

**Quick fixes:**
1. Test API in browser (simple GET requests)
2. Check if API endpoint is actually running
3. Disable proxy: Settings → Proxy → ❌ Use system proxy
4. Disable SSL verification (testing only): Settings → General → ❌ SSL certificate verification
5. Increase timeout: Settings → General → Request timeout in ms
6. Try Postman desktop instead of web (CORS doesn't apply)


### Error: "Sync Error: Could not sync"

**What it means:** Workspace can't sync with Postman cloud.

**Causes:**
- Postman sync service down
- Network connectivity issues
- Authentication token expired
- Workspace permissions issue
- Too many API calls (rate limited)

**Quick fixes:**
1. Check [status.postman.com](https://status.postman.com/) → Sync status
2. Click "Sync" icon manually to retry
3. Sign out and sign back in (refreshes token)
4. Check internet connection
5. Disable sync temporarily: Settings → Sync → ❌ Sync
6. Export collection as backup (just in case)


### Error: "Network Error: getaddrinfo ENOTFOUND"

**What it means:** DNS can't resolve the API hostname.

**Causes:**
- API hostname doesn't exist
- DNS server issues
- Typo in URL
- VPN blocking DNS resolution

**Quick fixes:**
1. Verify URL is correct (typos happen)
2. Test DNS: `ping api.example.com` in terminal
3. Try IP address instead of hostname (if known)
4. Flush DNS cache:
   - **Windows:** `ipconfig /flushdns`
   - **Mac:** `sudo dscacheutil -flushcache`
5. Change DNS server (Google DNS: 8.8.8.8, Cloudflare: 1.1.1.1)
6. Disable VPN temporarily


### Error: "Error: self signed certificate in certificate chain"

**What it means:** SSL certificate is self-signed or untrusted.

**Causes:**
- Development/staging API uses self-signed cert
- Corporate proxy injecting certificates
- MITM proxy/firewall
- Expired SSL certificate

**Quick fixes:**
1. **For development/testing only:** Disable SSL verification
   - Settings → General → ❌ SSL certificate verification
2. Add CA certificate: Settings → Certificates → CA Certificates
3. Use `http://` instead of `https://` (if API supports it)
4. Contact API provider about certificate issue

**⚠️ Warning:** Never disable SSL verification for production APIs.


### Error: "Collection Runner: Error while running scripts"

**What it means:** Pre-request or test script failed.

**Causes:**
- JavaScript syntax error
- Variable not defined
- Script timeout
- Missing library/dependency

**Quick fixes:**
1. Open Postman Console: View → Show Postman Console
2. Check console for error details
3. Verify variable names are correct
4. Test script in individual request first
5. Check for typos in script
6. Simplify script to isolate issue

**Example common error:**
```javascript
// ❌ Wrong
pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);  // Wrong method
});

// ✅ Correct
pm.test("Status code is 200", function () {
    pm.expect(pm.response.code).to.equal(200);
});
```


### Error: "Monitor Run Failed"

**What it means:** Scheduled monitor couldn't run collection.

**Causes:**
- Postman Monitors service down
- Collection has errors
- Environment variables missing
- Request timeout
- API endpoint down
- Rate limit exceeded

**Quick fixes:**
1. Check [status.postman.com](https://status.postman.com/) → Monitors
2. Run collection manually first (test it works)
3. Check monitor run logs for specific error
4. Verify environment variables are set
5. Increase monitor timeout (default 5 min)
6. Check API endpoint is accessible from Postman cloud IPs


### Error: "Mock Server: No matching requests"

**What it means:** Mock server couldn't find matching example.

**Causes:**
- No saved example for request
- Request path/method doesn't match
- Query params/headers don't match
- Mock server configuration issue

**Quick fixes:**
1. Add example response to request
2. Verify request method matches (GET, POST, etc.)
3. Check request path exactly matches
4. Use wildcards in mock matching
5. Check mock server URL is correct
6. Review mock server logs


## Quick Fixes: Postman Not Working?

### Fix #1: Restart Postman (The Classic)

**Why it works:** Clears cache, resets sync, refreshes authentication.

**How to do it right:**

**Windows:**
1. Close Postman (X button)
2. Open Task Manager (`Ctrl+Shift+Esc`)
3. Find "Postman" processes → End Task (all instances)
4. Relaunch Postman

**Mac:**
1. Quit Postman (`Cmd+Q`)
2. Force quit if needed: `Cmd+Option+Esc` → Postman → Force Quit
3. Relaunch

**Linux:**
```bash
pkill -9 postman
postman &
```

**Pro tip:** Clear process fully before restarting—just closing window isn't enough.


### Fix #2: Check Your Internet Connection

**Postman needs internet for:**
- Workspace sync
- Account authentication
- Monitors and Mock Servers
- Collection imports
- API calls (unless local)

**Test your connection:**

```bash
# Ping Postman's servers
ping postman.com
```

**Good response:**
```
Reply from 104.26.10.195: bytes=32 time=25ms TTL=57
```

**Bad response:**
```
Request timed out.
```

**Speed test:**  
Visit [fast.com](https://fast.com) or [speedtest.net](https://speedtest.net)

**If connection is slow:**
1. Restart router (unplug 30 seconds)
2. Check firewall isn't blocking Postman
3. Disable VPN temporarily
4. Try different network (mobile hotspot)
5. Contact IT if corporate network


### Fix #3: Clear Postman Cache

**Why it helps:** Corrupted cache causes sync issues, request failures.

**Desktop App:**

**Windows:**
1. Close Postman
2. Delete cache folder:
   ```
   %APPDATA%\Postman\Cache
   ```
3. Delete workspace data (nuclear option):
   ```
   %APPDATA%\Postman\IndexedDB
   ```
4. Restart Postman

**Mac:**
1. Quit Postman
2. Delete cache:
   ```bash
   rm -rf ~/Library/Application\ Support/Postman/Cache
   ```
3. Delete workspace data (nuclear option):
   ```bash
   rm -rf ~/Library/Application\ Support/Postman/IndexedDB
   ```
4. Restart Postman

**Linux:**
```bash
rm -rf ~/.config/Postman/Cache
rm -rf ~/.config/Postman/IndexedDB
```

**Web App:**
1. Clear browser cache for postman.co domain
2. Sign out and sign back in

**⚠️ Warning:** Deleting IndexedDB removes local workspace data. Make sure workspace is synced first!


### Fix #4: Update Postman

**Outdated app = bugs and compatibility issues.**

**Check version:**
- Postman → Settings → About
- Current version (as of Feb 2026): 11.x

**Update desktop app:**
1. Postman → Help → Check for Updates
2. If available, download and install
3. Or download latest from [postman.com/downloads](https://postman.com/downloads)
4. Restart Postman

**Auto-updates:**
- Settings → Update → ✅ Automatically download updates

**Web app:**
- Always latest version (no updates needed)


### Fix #5: Check Proxy Settings

**Postman respects system proxy, which can cause issues.**

**Disable proxy:**
1. Settings → Proxy
2. ❌ Use the system proxy
3. ❌ Add a custom proxy configuration
4. Try request again

**If you need proxy:**
1. ✅ Add a custom proxy configuration
2. Enter proxy details (HTTP proxy, HTTPS proxy)
3. Add bypass list (e.g., `localhost, 127.0.0.1`)
4. Test connection

**Corporate proxy:**
- Contact IT for correct proxy settings
- May need authentication credentials
- May need to add SSL certificates


### Fix #6: Disable SSL Verification (Testing Only)

**⚠️ For development/testing only—never in production!**

**When to use:**
- Testing local APIs with self-signed certificates
- Corporate proxy with custom certificates
- Development environments

**How to disable:**
1. Settings → General
2. ❌ SSL certificate verification
3. Try request again

**Better solution:**
1. Settings → Certificates
2. Add your CA certificate
3. Keep SSL verification enabled


### Fix #7: Check Workspace Sync Status

**Workspace sync issues are common.**

**Check sync status:**
1. Look for cloud icon in bottom-right
2. ✅ Green = synced
3. ⚠️ Orange = syncing
4. ❌ Red = sync error

**Force sync:**
1. Click cloud icon → "Sync Now"
2. Wait for sync to complete
3. Check for errors

**Disable sync (work offline):**
1. Settings → Sync
2. ❌ Sync
3. Work locally (no cloud sync)
4. Re-enable when needed

**Export collection (backup):**
1. Collection → ⋯ → Export
2. Save as Collection v2.1 (recommended)
3. Keep backup safe


### Fix #8: Sign Out and Sign Back In

**Refreshes authentication token, fixes account issues.**

**How to do it:**
1. Postman → Sign Out
2. Close Postman completely
3. Reopen Postman
4. Sign back in
5. Wait for workspace to sync

**What it fixes:**
- Authentication errors
- Sync issues
- Team workspace access
- Monitor/Mock Server permissions


### Fix #9: Reinstall Postman (Nuclear Option)

**When nothing else works:**

**Windows:**
1. Settings → Apps → Postman → Uninstall
2. Delete data folder (optional, removes all local data):
   ```
   %APPDATA%\Postman
   ```
3. Download from [postman.com/downloads](https://postman.com/downloads)
4. Install fresh
5. Sign in (workspace syncs back)

**Mac:**
1. Drag Postman to Trash
2. Delete data folder (optional):
   ```bash
   rm -rf ~/Library/Application\ Support/Postman
   ```
3. Empty Trash
4. Download from [postman.com/downloads](https://postman.com/downloads)
5. Install
6. Sign in

**Linux:**
```bash
sudo apt remove postman
rm -rf ~/.config/Postman
# Download and install latest .deb or .tar.gz
```

**Pro tip:** Your collections are in the cloud. Reinstalling won't lose them (if they were synced).


## Postman Desktop vs Web: Which to Use?

### Postman Desktop App

**Advantages:**

Quick API test on any machine? → Web
```

**Pro tip:** Install Postman Agent to call localhost from web version.


## Postman API Not Responding?

### Issue: Requests Timing Out

**Causes:**
- API endpoint is down (not Postman)
- Network firewall blocking
- Request timeout too short
- API server slow/overloaded

**Troubleshoot:**

**1. Increase timeout:**
- Settings → General → Request timeout in ms
- Try `0` (no timeout) for testing
- Default is 0 (no timeout)

**2. Test API availability:**
```bash
# Test if API is reachable
curl -I https://api.example.com

# Check response time
curl -w "Time: %{time_total}s\n" -o /dev/null -s https://api.example.com
```

**3. Check API status:**
- Visit API's status page
- Check if endpoint is actually working
- Test with another tool (cURL, browser)

**4. Check network:**
- Firewall blocking requests?
- VPN interfering?
- Corporate proxy timeout?


### Issue: 401 Unauthorized

**Causes:**
- Invalid API key/token
- Expired authentication
- Wrong auth header
- Incorrect auth type

**Troubleshoot:**

**1. Verify API key:**
- Check API key is correct (copy-paste fresh)
- Verify not expired
- Check API dashboard for valid keys

**2. Check auth type:**
- Authorization tab → Type
- API Key vs Bearer Token vs Basic Auth
- Check API documentation for correct type

**3. Check header format:**
```
❌ Wrong:
Authorization: my-api-key-here

✅ Correct:
Authorization: Bearer my-api-key-here
```

**4. Test auth in Postman Console:**
- View → Show Postman Console
- Check request headers sent
- Verify auth header is present


### Issue: CORS Error (Web Only)

**Error message:**
```
Could not get any response
This seems like the web request was prevented by CORS policy
```

**What it means:** Browser blocking cross-origin request.

**Solutions:**

**1. Use Postman Desktop App (recommended):**
- Desktop app bypasses CORS
- No browser restrictions

**2. Install Postman Agent:**
- [Download Postman Agent](https://www.postman.com/downloads/postman-agent/)
- Allows web version to call localhost
- Bypasses some CORS issues

**3. Fix API CORS headers (if you control API):**
```javascript
// Add to API response headers
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Access-Control-Allow-Headers: Content-Type, Authorization
```

**4. Use proxy/CORS proxy (testing only):**
- Not recommended for production
- Security risk


## Postman Collections Not Syncing?

### Issue: Changes Not Appearing in Team

**Causes:**

- Mock server URL wrong
- No matching examples
- Mock server deleted/disabled

**Troubleshoot:**

**1. Check Mock Server status:**
- [status.postman.com](https://status.postman.com/) → Mock Servers

**2. Verify mock URL:**
- Collection → Mocks → Copy URL
- Check URL is correct
- Example: `https://{{mockId}}.mock.pstmn.io`

**3. Add example responses:**
- Requests need saved examples
- Add → Example
- Save response body, status, headers

**4. Check mock matching:**
- Request method must match (GET, POST, etc.)
- Request path must match exactly
- Query params/headers matching (optional)

**5. Test mock URL:**
```bash
curl https://your-mock-id.mock.pstmn.io/endpoint
```


### Issue: Mock Returns Wrong Response

**Causes:**
- Multiple examples (returns first match)
- Request doesn't match exactly
- Header/query param mismatch

**Solutions:**

**1. Review mock matching:**
- Mocks return first matching example
- Make examples more specific

**2. Use query params for variants:**
```
Example 1: GET /users?status=active
Example 2: GET /users?status=inactive
```

**3. Check mock server logs:**
- Mock settings → View Logs
- See which example was matched

**4. Use x-mock-match-request-headers:**
```
Header: x-mock-match-request-headers: Authorization
```
- Forces header matching for example selection


## Postman Interceptor Not Working?

### What is Interceptor?

**Postman Interceptor** is a Chrome extension that:
- Captures browser requests

## Prevent Future Issues

### 1. Keep Postman Updated

**Enable auto-updates:**
- Settings → Update → ✅ Automatically download updates

**Why it matters:**
- Bug fixes
- Performance improvements
- New features
- Security patches

**Check version regularly:**
- Postman → Settings → About


### 2. Export Collections Regularly

**Don't rely only on cloud sync.**

**Backup routine:**
1. Collection → ⋯ → Export
2. Save as Collection v2.1
3. Store in version control (Git)
4. Automate with Postman API

**Pro tip:** Use Git for collection version control:
```bash
# Export collection
# Commit to Git
git add collection.json
git commit -m "Update API collection"
git push
```


### 3. Use Environment Variables

**Don't hardcode values.**

**Why:**
- Easy to switch environments (dev/staging/prod)
- No need to edit requests manually
- Secure (secrets not in collection)
- Team collaboration easier

**Best practices:**
```
❌ Bad: https://api.production.com/users

✅ Good: {{baseUrl}}/users
Environment: baseUrl = https://api.production.com
```

**Sensitive data:**
- Use environment variables for API keys
- Don't commit .postman_environment files to Git
- Use Postman Vault (Enterprise)


### 4. Monitor Your APIs Proactively

**Don't wait for users to report issues.**

**Use Postman Monitors:**
- Schedule collection runs every 5-60 minutes
- Get alerts on failures
- Track response times
- Monitor uptime

**Set up health checks:**
```javascript
pm.test("API is up", function () {
    pm.response.to.have.status(200);
    pm.expect(pm.response.responseTime).to.be.below(2000); // 2 sec
});
```

**Alternative monitoring:**
- [API Status Check](https://apistatuscheck.com) for external monitoring
- Combine with Postman for comprehensive coverage


### 5. Use Collections Properly

**Organize for team success.**

**Best practices:**

**1. Folder structure:**
```
Collection: My API
├── Authentication
├── Users
│   ├── Get User
│   ├── Create User
│   └── Update User
├── Products
└── Tests
```

**2. Add documentation:**
- Describe each endpoint
- Include example responses
- Document required headers

**3. Use pre-request scripts:**
```javascript
// Auto-generate timestamp
pm.environment.set("timestamp", new Date().toISOString());

// Auto-refresh token
if (!pm.environment.get("token")) {
    // Get new token
}
```

**4. Add tests:**
```javascript
pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

pm.test("Response time is acceptable", function () {
    pm.expect(pm.response.responseTime).to.be.below(1000);
});
```


### 6. Have Backup Tools Ready

**Don't rely on one tool.**

**Quick alternatives:**

**cURL (always available):**
```bash
curl -X GET https://api.example.com/users \
  -H "Authorization: Bearer YOUR_TOKEN"
```

**HTTPie (friendlier syntax):**
```bash
http GET https://api.example.com/users \
  Authorization:"Bearer YOUR_TOKEN"
```

**Thunder Client (VS Code):**
- Install in VS Code
- Similar to Postman
- Lightweight alternative

**Newman (CLI for Postman):**
```bash
npm install -g newman
newman run collection.json
```


## Key Takeaways

**Before assuming Postman is down:**
1. ✅ Check [Postman Status](https://status.postman.com/)
2. ✅ Test simple request (GET httpbin.org/get)
3. ✅ Try Postman web vs desktop
4. ✅ Search Twitter for "Postman down"

**Common fixes:**
- Restart Postman + clear cache (fixes 50% of issues)
- Update to latest version
- Disable proxy/SSL temporarily
- Check API endpoint is actually running (not Postman)
- Sign out and sign back in

**Request issues:**
- Check Postman Console for details
- Test API with cURL to isolate issue
- Increase timeout for slow APIs
- Desktop app bypasses CORS (web doesn't)

**Sync issues:**
- Check cloud icon status
- Force sync manually
- Export collections as backup
- Work offline if needed

**If Postman is actually down:**
- Monitor [status.postman.com](https://status.postman.com/)
- Work offline with desktop app
- Use Newman CLI or alternative tools
- Usually resolved within 1-3 hours

**Prevent future issues:**
- Keep Postman updated
- Export collections regularly
- Use environment variables
- Set up Postman Monitors
- Have backup tools ready (cURL, Newman)

**Remember:** Most "Postman down" issues are either API endpoint problems or local configuration—not Postman itself. Try the fixes in this guide before assuming Postman is down.
