Since I moved my server to ipv6 only federation broke. I'm guessing this server is acessible trough the cloudflare proxy, but the underlying server is unable to connect to mine
Edit:
This is what I get in the logs:
2023-09-27T19:17:23.955421Z DEBUG activitypub_federation::activity_queue: Activity https://lemmy.fbmac.net/activities/undo/506ed9a4-bfee-472f-8249-f802639eec8d was rejected by https://lemmy.world/inbox, aborting: Request error: error sending request for url (https://lemmy.fbmac.net/u/fbmac): error trying to connect: tcp connect error: Address not available (os error 99)
I think it kind of confirms, lemmy.world is unable to contact mine back.
What servers are really IPV6, so I can actually federate with something?
I'll let mine this way, someone has to be the first
can you try to browse anything from lemmy.fbmac.net from your instance to see if it works? I didn't find any other instance that it's able to federate yet
