Could not start Appium server. It's showing [Error Starting appium server: listen EADDRINUSE 0.0.0.0:4723]
If EADDRINUSE, Address already in use is the issue, 
do
ps aux | grep node
to get the process ids.
Then:
kill -9 PID
Doing the -9 on kill sends a SIGKILL.
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.
