Postman Not Working Fix | Is Postman Down Status

If Postman is not working for you, the issue is likely a local glitch with the desktop app (the “White Screen of Death”) or a connection handshake failure.

Here is how to fix the most common issues:

1. The “White Screen” or “Stuck Loading” Fix

If the app opens but stays blank or spins forever, your local cache is corrupted. This is the most common Postman bug.

• The Fix (Windows):

  1. Close Postman completely (Task Manager > End Task).

  2. Press Windows Key + R, type %appdata%, and hit Enter.

  3. Find the folder named Postman and delete it.

  4. Relaunch the app. (You will need to log in again, but your collections are safe in the cloud).

• The Fix (Mac):

  1. Open Finder > Go > Go to Folder.

  2. Type ~/Library/Application Support/Postman and delete the folder.

2. “Agent Mode Unavailable” (Feb 12 Residual)

There was a specific outage regarding the Postman Desktop Agent just a few days ago (Feb 12). If you are using the Web version (go.postman.co) and it can’t “see” your local requests:

• Action: You must manually restart the Desktop Agent (look for the little Postman icon in your system tray/menu bar, right-click, and select “Quit,” then restart it).

3. “Could Not Send Request” / SSL Error

If the app loads, but every API call fails with “Error: connect ECONNREFUSED” or “SSL Error”:

• Disable SSL Verification: Go to Settings (Gear Icon) > General and toggle OFF “SSL certificate verification.” (This is often required if you are on a corporate VPN or testing localhost).

• Check Proxy: Go to Settings > Proxy and ensure “Use System Proxy” is unchecked if you are not actually using one.

4. Immediate Workaround: Use the Web Version

If the desktop app is completely broken, you can access your entire workspace immediately without installing anything:

• Go to: go.postman.co/build

• This runs the full Postman interface inside your browser (Chrome/Edge).
