I just searched for this community, as I wanted to link to their starting guide from my instance. I searched for [email protected] via my instance's search option, and now while I can visit it, it always appears empty.

I saw the same issue, but would like to provide some additional information (for my case): I searched for https://lemmy.world/c/mildlyinfuriating on my instance. According to https://join-lemmy.org/docs/en/administration/federation_getting_started.html, my expectation was I'll see the community within a couple of seconds.

My lemmy-log shows

My setup is based on docker-compose, https://join-lemmy.org/docs/en/administration/install_docker.html

Any ideas?

EDIT: It might be Centos 7 issue with default configuration or something I did in the past :-( I connected to lemmy_1 via docker exec and wasn't able to initiate any outgoing connection from within the container. Seems I'm filtering it somewhere.

Seems the lemmy-container was supposed to use nginx as a reverse proxy to reach other servers, but for some reason that didn't work. I added

lemmy:
    ....
    networks:
        ....
        - lemmyexternalproxy

Now it works... I assume there should be a better option for me to fix it, maybe something in the nginx.conf or so?
