Failed to bind to address (already in use) error with Visual Studio Mac API

Sure you can change the port every time you get that error or even restart your computer, here is the correct way to go about this

Find what is running on that port and kill the process

Terminal on mac

find the process number

lsof -i: <port number>
eg lsof -i:5001

Then kill the process number

kill -9 <process number>
eg – kill -9 1600
