How to Fix 'Could Not Get Response' Error in Postman

The Could not get response error in Postman usually happens when the server is unreachable, the URL is wrong, or there is a network issue. To fix it, check your request URL, ensure the server is running, and verify your internet connection or proxy settings.

Why This Happens

This error occurs when Postman cannot receive any response from the server. Common reasons include incorrect URLs, server downtime, network problems, or firewall blocking the request.

Headers:
Content-Type: application/json

Body:

  "name": "John"
}

Output

Check if the server is running and reachable.

The Fix

Verify the URL is correct and the server is running. If using localhost, ensure your server is active on the specified port. Also, check your internet or proxy settings to allow Postman to connect.
