So it looks like they’re pushing to us OK, but we’re struggling to push our stuff to them. I did just try to visit the site and got a 502 error so not sure if they’re having issues over there?

This link shows a bit more detail and you can see hexbear under “failing instances”. Lemmy.ml have the same problem, and I’m sure others will too. So either their incoming federation is broken or they’ve been offline enough for instances to automatically flag them as offline.

Will see if there is an easy fix for this, but hopefully the federation fix in 0.19.2 will prevent this from happening in the future (if this is what it causing the issue and not a config issue hexbear side).
