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:

    I’m using the config here: https://github.com/LemmyNet/lemmyBB/blob/main/docker/nginx.conf

    the only difference is that $lemmybb_domain is replaced with the bb ui domain name. Again, the normal lemmy ui works great, ansible install so everything including config is default.

    Is there something with the lemmy backend or UI I’m supposed to configure to let it know that lemmyBB exists?

            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?
