My first reaction was that this was a proxy issue since I’m running Hub , nodes are running on same machine.
Another but not sure due to different phone models?? since the App installed but failed to execute the test on iPhone 6(Only one test passed).

Appium server logs:

info: [debug] Responding to client with error: {“status”:13,“value”:{“message”:“An unknown server-side error occurred while processing the command.”,“origValue”:“elementId 2 could not be tapped”},“sessionId”:“d6fb23d8-4cf4-4644-838a-250a1a306f86”}

or is this something timout out issue ?? please help I’m struck on this issue for couple of days .Appreciate your help.
