I am using Appium version V1.15.0 and have already start the server successfully with the default Host: 0.0.0.0 and Port: 4723
But now when i try to start the server it shows me this error "Error Starting Appium server: listen EADDRINUSE 0.0.0.0:4723"
I have tried to solve this issue by changing the port but could not find any solution.
Suggest me if you guys have any better solution.
I have found the solution. After restarting my computer, i could successfully run the Appium server.
If anyone face the same problem. Please follow below steps:
1. Check if the port is listening to any other services.
      Open command prompt: Type netstat -a -b

Either kill that service or try with different port.
If both not working then restart your machine.

This way i have solved this problem.
Could not start Appium server. It's showing [Error Starting appium server: listen EADDRINUSE 0.0.0.0:4723]
