I have a lemmy-ui instance working correctly, fresh ansible install. I haven’t configured it yet, but it’s up and running and test posts work fine.

I’m mostly interested in lemmyBB, so I installed that according to “Alongside existing Lemmy instance (native)” install instructions.

Everything seems to work fine during install, systemctl status lemmy_bb.service shows:

            Here’s the config I use for the lemmy backend: https://github.com/LemmyNet/lemmy/blob/main/docker/prod/nginx.conf here’s my lemmy.hjson https://github.com/LemmyNet/lemmy/blob/main/docker/prod/lemmy.hjson

            like I said, aside from domain name and required variables, everything is default, running a fresh vps. Ansible install for Lemmy, “install along other instance” instructions for lemmyBB.

            No messing with ports. Fresh debian 10, debian 11, ubuntu 22, all with the same result:

            Lemmy-UI works fine, lemmyBB returns a 502.

              Are you using docker at all? If yes, can you share the output of docker ps?

              Also, can you share your /etc/systemd/system/lemmy_bb.service file?
