Python [Errno 98] Address already in use

Question

In my Python socket program, I sometimes need to interrupt it with Ctrl-C. When I do this, it does close the connection using socket.close().

Answer 1

run the command

fuser -k (port_number_you_are _trying_to_access)/TCP

example for flask: fuser -k 5000/tcp

Also, remember this error arises when you interput by ctrl+z. so to terminate use ctrl+c
