Rails Server Saves Exit (SocketError)

Rails noob is here. I try to work with Michael Hartl Ruby in the Rails Tutorial, but every time I start the rails server, it continues to Exiting and shows me a SocketError. Last weekend, I was able to start the server using wifi from startup, so I guess this has something to do with my internet connection / firewall? Today I ran into the same problem with the server in the library.

Any help is appreciated! Thanks in advance.

First you need to identify the rails server port identifier, so run the command below specifying a list of PIDs that works on 3000 ports

lsof -wni tcp:3000

PID column number to kill process:

kill -9 PID
0
