The process went through smoothly. I have also used the opportunity to split up a singular lemmy container into individual tasks - this has enabled a seemless upgrade process with no downtime, bar a few process quirks I need to work out.
There have been some federation fixes merged into this release, so the situation should definitely be improving overall!
I will make a more detailed write up of the whole setup later on, other admins might find it useful. Or not.
Sorry for a late reply, I think your federarion has only recently caught up.
Yes, lemmy.cafe was on 0.19.0, then one of the .1 RCs, then 0.19.2-rc.5 and, finally 0.19.2.
Thanks!
Seems restarting the server is the only way to make federation work at the moment.
Try enabling debug log for federation - helped for me. Phiresky guessed it's due to federation queries slowing down enough to not get stuck.
