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 and lemm.ee have the same issue as us, and I’m sure others will too. So either Hexbear’s 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).

Edit: feel like I need to expand in case anyone is curious. From what I can tell the issue doesn’t lie with lemmy.zip which I’ve determined two ways, one being that we are receiving stuff from them just fine and the second being that other servers appear to be having the same issue with flagging hexbear as failing. The next retry scheduled appears to be tomorrow (12th) some 24 hours after the last try the server made. If successful, I assume our server will then proceed to send all updates to hexbear as will the other servers, but this is the first time I’ve seen federation broken this way around so I can’t say for definite what will happen. I’ve reached out to a hexbear admin on matrix I’ve spoken to previously to see if they’re aware of this. I don’t really keep up with other server’s uptime so not sure if they’ve been offline a significant amount recently? This might cause all the servers to flag hexbear as failing. Otherwise I’m not sure the cause of it. But I’m pretty confident that federation on lemmy.zip is working fine and this is a hexbear issue.
