Address already in use error when starting

Everything else is installed and nginx is working; I left the IP and port default because that’s what the guide says to do when using the default nginx config but upon running sudo -Hu akkoma MIX_ENV=prod mix phx.server the process crashes after a few seconds and gives the following error output.


I’m pretty sure Elixir isn’t the problem since I’ve checked and re-checked that it’s up to date and it didn’t give me any other problems.

this means you have something else binding to port 4000, nothing we can solve here, you’ll have to look on your machine and find out what you’re running
