Once updated iOS from 15.2 to 15.4 on real devices, the get screenshot function doesn’t work anymore.

Details

The problem started once update iOS from 15.2 to 15.4. Updated Xcode too to 13.3 to handle with new iOS.

While trying to get screenshot at the end of a test, the Appium server throws an exception, the message: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to the remote server. Original error: socket hang up

We experienced similar issues with iOS 15.1 and Appium 1.22 (desktop), solution was using Appium CLI 1.22.2, but now it the last stable version.

We found some related issues from the past, maybe it is the same problem, a couple of they are related to this 15262
