Since 0.19, the federation does not work correctly anymore, and requires regular restart of the Lemmy process (as far as I understand). Just in case you also noticed that it became a bit more empty in here.
On that note, maybe we can postpone future lemmy updates until the most major issues are ironed out? Then we would not suffer so much from these issues in the future :)
Otherwise, thank you a lot for running sopuli, it is a pleasure to be here!
