Built with

You are experiencing the following issue

Your workspace cannot be loaded and you are encountering one of these error messages:

  • Unable to load data
  • You are offline
  • Unable to fetch data

What to expect

Communication with Postman servers can only happen successfully through secure WebSockets. If those are not in use, the system considers you offline.

How to unblock yourself

  • Verify your access to the Postman web app.
    • Remove local data if you’re unable to reproduce the issue on the Postman web app.
  • Try switching to a different network. If you are using the Postman app, a VPN or proxy on your computer might be enabled, preventing access to Postman services.
    • Contact your IT team and request that they configure the network firewall to permit WebSocket connections for Postman.
  • Sign out of the Postman app and then sign back in.
  • Note: If you’re using Postman locally without signing in to a Postman account, export your data before signing out because signing out will completely delete your local data.
  • Contact your Internet service provider (ISP) to verify if there’s an internet outage in your area.

If you’re still facing this issue after trying the troubleshooting options outlined above, submit a support request and include the following information:

  • The troubleshooting steps you’ve already tried.
  • Whether or not you can use the Postman Web app.
  • A screenshot or a screen recording of the issue.
  • A copy of your app logs if you experience the issue on the Postman desktop app.
  • A copy of your HAR files if you experience the issue on the Postman web app.
