[Resolved] Federation issue between lemmy.world and fanaticus

Hi, everyone! A few of you have brought to my attention that lemmy.world is not receiving new posts from fanaticus and vice versa.

I've been debugging it and haven't been able to resolve the issue. Fanaticus' nginx logs are reporting that all requests incoming from lemmy.world are returning a 400. Additionally, we've found that outbound requests to lemmy.world from fanaticus are being responded to with a CloudFlare page.

I am reaching out to the lemmy.world admins to see if we can get fanaticus's IP whitelisted on their CF config. I'll update this thread with any news.
