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/reddit@lemmy.ml

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

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/reddit@lemmy.ml

and it receives a response.

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

             at src/root_span_builder.rs:16
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?
