I'm not sure if I should make a new post or keep this in a single thread, anyway, I've managed to get the front page to load, but can't get any farther.

I used the instructions from @jax@lemmy.cloudhub.social's branch, particularly their nginx config.

I'm running the whole docker-compose setup behind my own nginx reverse proxy, which is set to proxy requests to the docker nginx (and also handles SSL). I modified the docker-compose.yml to bind the host port on 9001, then my main nginx config looks like this:

http {
    server {
        listen 443 ssl http2;
        server_name lemmy.villa-straylight.social;
        ssl_certificate /etc/letsencrypt/live/<redacted>
        ssl_certificate_key /etc/letsencrypt/live/<redacted>

        location / {
            proxy_set_header Host $host;
            proxy_pass http://localhost:9001;
        }
    }
}

The front page loads, but pretty much anything else I do results in an endless spinner. The only possible problem I see is this in the docker terminal output:

WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: WebSocket upgrade is expected. NoWebsocketUpgrade
