swift server side server socket error

Question

I'm suffering from server problem on both perfect and vapor ..

The server working for only one time , and once after i update the project and rebuild it, the server response does not update any more.

I got this error ... from vapor in Xcode

No command supplied, defaulting to serve...
Starting server on 0.0.0.0:8080
Serve error: Sockets Error: Failed trying to bind to the address

Identifier: Sockets.SocketsError.bindFailed
Program ended with exit code: 0

I googled alot , but did not figure out the problem

Finally : when i restart the mac , the server worked good only for one time , and the problem returned the same .

Answer 1

Seems like a process is using port 8080. Try running lsof -i :8080 from the terminal and kill it's PID with kill -9 PID
