[SOLVED] How to configure Lemmy instance nginx proxy for websockets? (self.selfhosted)

I'm playing around with my own instance of Lemmy but I keep getting a "websocket connection failed" error in my console. I'm having a really hard time understanding how to set up nginx for websockets - I'm more used to Apache and not familiar with WS at all. Is there documentation hiding somewhere that will help me set up my proxy forwarding properly?

EDIT: Solved! Check out my solution here: https://lemmy.world/comment/141648. Thanks everyone!

I might be. See my response here: https://lemmy.world/comment/101425

I would recommend you ditch the second nginx layer. It's a waste of resources and it can cause a multitude of issues if the configuration isn't done correctly.

If you are hosting multiple domains on the same server, disable the nginx container in the docker-compose.yml file and copy Lemmy's nginx config into your system's nginx config (e.g. /etc/nginx/).
- If you go this route you should also delete the lemmyexternalproxy network, delete internal: true on the lemmyinternal network (required to enable port forwarding) and add port forwards to the lemmy and lemmy-ui docker services. Here's what that would look like: https://www.diffchecker.com/vjfEFuz6/
If you are not hosting multiple domains on the same server, simply edit the port forwards in the docker-compose.yml file for the proxy service to bind to whatever your external facing IP is.

AHA. That did it. Getting rid of the host's nginx fixed the issue. Now websockets work as expected and I can log in!
