Can't logging when using NPM/Nginx Proxy Manager

[woj-tek]

Do not use this for questions or support. Use !lemmy_support. ^^ unfortunately is overloaded hence asking here

I tried to setup lemmy instance and I can access it just fine but can't log-in.

In the (docker) logs I see:

lemmy-lemmy-1     | 2023-06-12T16:15:19.489000605Z 2023-06-12T16:15:19.488524Z  WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: WebSocket upgrade is expected.

In the browser I see:

1. request

There was another issue that mention using NPM (#3019) but the issue seems to be slightly different there. I do have network separation and set services.proxy to be in the same network as NPM (so NPM could forward traffic to proxy/nginx and then it would go to lemmy).

Anyone else with similar setup?

Can you post your nginx config?

I'm using the default from https://join-lemmy.org/docs/en/administration/install_docker.html.

I also tried the one from the linked issue (https://github.com/LemmyNet/lemmy/issues/3019#issuecomment-1587583582) but without any luck.

With a fresh mind... NPM has option "WebSocket support", which is disabled by default... my bad :-)

I'm running into this, too. Where/how do I enable NPM's "WebSocket support" option? Sorry if it is obvious, but I am really unfamiliar with NPM.
