[SOLVED] How to configure Lemmy instance nginx proxy for websockets?

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!

The nginx config provided in the Docker installation part contains everything needed for nginx. If you are installing lemmy directly on the machine you may need to use different upstreams.

The websocket part is basically the

            # proxy common stuff
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";

part in the nginx config on that page.

I seem to be having a lot of lag at the moment, and my post was created twice so I'm just going to delete the other one and start from here...

So I have this set up per the instructions. My instance is on a Digital Ocean instance, and I'm using nginx on the host to point to localhost:1235, but that's about all that conf file is doing. Is there something else I need to do?

Ok, just to understand what you did. You got an Digital Ocean droplet with Docker and used the instructions in the link I posted or different ones?

If you are using the instructions from my link nginx will also run in a docker container, which means that your upstream will not be on localhost, but rather the lemmy and lemmy-ui containers.

If you did install it locally then localhost:1235 could be correct.
