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?
