I run a Lemmy instance at lemmy.sedimentarymountains.com. It has been working for some time. 6 days ago it stopped getting updates from communities it was federated with. If I view all posts by active there is nothing newer than 6 days old. I checked disk space on the server, there is plenty. I don’t appear to be running out of any other resource. I redeployed the ansible playbook which didn’t do anything other then reload some services. I rebooted the server with no change in behavior. I am running 0.18.4 on Ubuntu 22.04.2 LTS.
I did notice that when I searched for !lemmy_support@lemmy.ml it started to pull fresh posts, but only from this community. I tried manually searching for a few other communities and I got a one time update of fresh content from them. I’m not sure what has changed. Is there a log I can review for federation issues?
I originally tried to post this from my instance but it didn't ever show up here. I've created an account on lemmy.ml to post this.
Your SSL certificate is expired, as of 6 days ago, federation won't work without HTTPs.
Once you fix that, I would assume it should start working again (it may take a bit for federation to resume once this is done)
It's the certificate on my reverse proxy! When I look at my own page I see the real certificate as its hosted within my house.
Thanks for the help!
