You are experiencing one of the following issues
The Desktop Agent keeps running, but the application doesn’t open.
I am getting the error Desktop Agent Unavailable when I want to select Send.
The Desktop Agent is disconnected.
Unblock yourself
In the Postman Web app, make sure you have selected the Desktop Agent.
Make sure you have downloaded the latest version of the Desktop Agent and that it is running.
To do so, look for the Postman icon on your desktop’s menu bar. The menu should show that the Desktop Agent is connected .
If you’re considering using the Desktop app, make sure you’re downloading the correct file on the download page . Select Download the App .
Note: You need the Desktop Agent to use the Postman Web app, which is different from the Postman Desktop app.
If the Desktop Agent reads any error, select Check for updates > open the Desktop agent and refresh the web page.
Ensure no VPN or proxy is in use that prevents connecting to Postman by allowing all websockets required to work with the Postman application .
Note: Try to reproduce the issue on a different network or device to help find the cause.
Disable all browser plugins as a test to ensure they do not interfere with the agent connection.
Things to note
Chromium-based browsers like Google Chrome, Microsoft Edge, and Brave are preferred.
Choose an Agent as per your API testing environment.
The Desktop agent doesn’t run behind a proxy.
The Desktop agent listens to port 10533.
