Solution

I found the answer to this problem. The solution is to remove io.appium.uiautomator2.server and io.appium.uiautomator2.server.test from the device.

1. Make sure appium server is not executing.
2. Connect your android device with USB, also verify that device is connected properly by using command:

   adb devices
   

3. Execute below commands:

   adb uninstall io.appium.uiautomator2.server
   adb uninstall io.appium.uiautomator2.server.test
   

4. Start appium server
5. Start executing appium test cases

This did not resolve my problem. I am getting this when running tests in parallel, any help?

[Vasanth]

I'm facing same issue in iOS ? any help ?

[T.Che]

this helps when the socket hangs up.

[Ahtisham Ilyas]

My issue got resolved after using these commands, thanks mate.

[deepak]

it would be great if someone could explain why this is happening, and how the fix works
