Actually there is now a fix, https://github.com/LemmyNet/lemmy-ansible/pull/114
But it seems that instances that update to the latest RC do not just automatically get that fix into their nginx config. I have worked with a instance owner and he had to, despite updating, manually update the config. After that federation worked again.
