It smells like our federation works fine, but I don't know that we're receiving all inbound events, especially from your server. I had to manually pull this. I imagine the ACK from our server RE: your subscription is also getting lost, that or your outbound subscription request isn't making it in.
I cranked up the federation log levels to try and sort this out. Here's a
logs | grep -ie fosscad.io:2025-10-01T00:45:06.965548Ztalks about inbox rejection and had some HTML after it -- HTTP 400 from nginx.Ping me in the GunCAD Index Matrix chat if you can.
EDIT: Also I'm going to search for this post from your site so it federates in and you get an inbox notif.
EDITEDIT: That didn't work lol
EDITEDITEDIT: Oh, it seems like we might be able to POST to your endpoint fine. I know last night I saw some 'Invalid Signature' issues, but it looks like you resolved them.
Yeah I have NGINX behind another reverse proxy + CloudFlare. And then was still setting X-Forwarded-For at NGINX which was messing up signatures all the way.
I'm hoping things re-sync.
I'm able to cross-post both ways, and see comments relatively quickly.
Will get on Matrix.
You just jumped from 120 lagging to 120 up-to-date so I think you're good now man.
I, uh, also fucked up a couple things that I fixed a few hours ago lol
Okay - I'm getting on Matrix too so we have a place to discuss if needed. But yeah seems to be working more consistently on my end too.
Looking at it again. We have 121 out of date, but it's only 2 behind.
This means our DB/send portion is behind? Or is it failing to receive acks?
Check now that you've made a post. I think it might just be a heuristic and if you don't have events for 10 minutes it trips
That seems to be the case. Thanks. TIL.
