Considering the timing this is probably a side effect of .world upgrading to 0.19.3 and their federation kicking into "higher" gear. I see 20-50 warnings like these in logs every minute all from lemmy.world.
I am guessing .world thinks at least one of my users are subscribed to a community but they are not (?) so my instance drops the federation (?)
