Is Postman Down? Live status & outage reports

Service info and troubleshooting

App Won't Launch or Crashes on Start

If Postman desktop refuses to open or crashes immediately, the most common culprit is a corrupted cache. Navigate to %AppData%\Postman (Windows) or ~/Library/Application Support/Postman (macOS), delete the Cache folder, and relaunch. If that doesn't help, reinstall the app — but export your collections first via File → Export.

Requests Returning Connection Errors

When every request fails with 'Could not get any response' or 'ECONNREFUSED', check a few things in order:

• Make sure the target server is actually running and accessible from your machine via curl or browser
• Verify the URL scheme — http vs https matters, and a wrong port kills the request instantly
• Disable SSL certificate verification in Settings → General if you're hitting a local or self-signed cert environment
• Check if a proxy is configured under Settings → Proxy that shouldn't be there

Environment Variables Not Resolving

If {{variable}} stays as a literal string in your request instead of resolving to a value, you've likely selected the wrong environment or none at all. Use the environment dropdown in the top-right corner and confirm the variable name matches exactly — Postman is case-sensitive here. Also check that the variable is set in the active scope, not just defined in a collection with no environment selected.

Sync Failing or Collections Not Updating

Cloud sync sometimes gets stuck after a network interruption. Sign out from the avatar menu, sign back in, and wait 30–60 seconds for the sync indicator to settle. If collections still don't match across devices, use File → Export on the up-to-date machine and import manually on the other.

Console Shows 401 or 403 on Every Call

Authentication errors almost always mean a token is expired or the auth header isn't being sent. Open the Postman Console (View → Show Postman Console) and inspect the actual request headers — not the UI, but what was really sent. If you use collection-level auth, make sure the request's own auth is set to 'Inherit from parent', not 'No Auth'.
