Dealing with the frustrating ‘socket hang up’ error in Postman can be a daunting task for any developer trying to streamline their API testing process. This pesky error can halt your progress and leave you scratching your head for a solution. But fear not, as I’m here to provide you with a comprehensive guide on how to solve the ‘socket hang up’ error in Postman.

Troubleshooting ‘Socket Hang Up’ Error in Postman

Solving the frustrating “socket hang up” error in Postman can be a real challenge, especially when you’re trying to get your API requests running smoothly. But don’t worry, I’m here to guide you through a series of troubleshooting steps that might just save your sanity.

First off, let’s talk about the most common causes of this error. It could be due to a mismatch in HTTP versions between your client (Postman) and server. If your client is expecting HTTP/2 while your server only supports HTTP/1.1, you’ll get this error.

To fix this, make sure both parties are speaking the same protocol language.

Another culprit might be a network proxy or VPN that’s causing issues. Try disabling any proxies or VPNs you’re using and see if that resolves the problem. I’ve heard tales of Postman struggling to connect through certain VPNs, so it’s worth a shot.

Now, let’s dive into some more technical solutions. If you’re getting this error when running a collection in Postman, try increasing the timeout period for your requests. You can do this by adding a “timeout” property to your request settings and setting it to a higher value (in milliseconds).

For example: `{“request”: {“method”: “GET”, “url”: “”, “timeout”: 60000}}`

If that doesn’t work, try checking the URL of your API endpoint. Sometimes, Postman can get confused if the URL is incorrect or has typos. Double-check your URL and make sure it’s correct.


  • Check for HTTP version mismatches between client and server
  • Disable network proxies or VPNs
  • Increase timeout period for requests
  • Verify the URL of your API endpoint
  • Update Postman to the latest version

If none of these steps work, try updating Postman to the latest version. Sometimes, bugs get squashed and new features get added, which might just fix your issue.

By following these troubleshooting steps, you should be able to solve the pesky “socket hang up” error in Postman and get back to testing your API requests with ease.

In conclusion, solving the ‘socket hang up’ error in Postman requires a methodical approach and attention to detail. By checking for HTTP version mismatches, disabling network proxies or VPNs, increasing timeout periods for requests, verifying API endpoint URLs, and updating Postman to the latest version, you can successfully navigate through this error and ensure seamless API testing experience. Don’t let the ‘socket hang up’ error derail your progress – arm yourself with these troubleshooting techniques and conquer any challenges that come your way in Postman.
