Change webpack file to use 127.0.0.1 instead of local host

I changed the Port to 8001 :sweat_smile:
It works past that step :face_with_peeking_eye:

Thank you :wave:t4:

I ran into this a lot recently and sure enough changing the port temporarily fixes the issue but doesn’t address the root cause, which is that a previous instance of your app (or some other process) is still running on port 8000.

To find the process (for Mac/*nix users) run:

lsof -i tcp:8000

…that will get the pid of the running process, then kill it with:

kill <processPid>
