on windows

netstat -anp | find "your application port number"` --> find PID

taskkill /F /PID

on Linux,

netstat -ntpl | grep "your application port number"

kill pid // pid you will get from previous command

on Mac OS

lsof -n -iTCP:"port number"

kill pid //pid you will get from previous command
