I am running 0.17.3 version of Lemmy installed by docker-compose, in front of it I am running NPM (ngnix proxy manager) which handles all of my public facing docker images.

The local site seems to function except for one area, I can’t search for or properly federate other instances. I believe I have narrow the problem down to one particular function:

https://lemmy.timgilbert.be/c/[email protected]

This results in a response in the browser:

404: couldnt_find_community

And an error log in docker logs for the server:

2023-06-13T01:48:29.196432Z  WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: couldnt_find_community: Failed to resolve actor for reddit@lemmy.ml

             at src/root_span_builder.rs:16
LemmyError { message: Some("couldnt_find_community"), inner: Failed to resolve actor for reddit@lemmy.ml, context: "SpanTrace" }

If I hit this same URL but from a working site:

https://lemmy.world/c/[email protected]

and it receives a response.

I also see other other errors/warning all of which indicates some problem with my settings for in-bound:

LemmyError { message: None, inner: cant accept local object from remote instance, context: "SpanTrace" }

I suspect that it has to do with having two NGINX wrappers, one that is setup by Lemmy’s docker-compose and one for my NPM.

Anyone else have similar problems?

    I had a similar problem but just used nginx as the proxy from their installation guide.

    What I found out is that the lemmy container needed to be exposed to an external network, but from the docker-compose file it was limited to an internal network only (named lemmyinternal). I ended up adding the lemmyexternalproxy network to the lemmy container as well and that fixed my issue.

    Try other instances, lemmy.ml is down right now. It’s been going up and down all day. And when it’s not down, federation is hours behind if not completely broken.

    You can see it on lemmy.world because they were already federated, and you’re seeing the cache.
