After some sleep, I have to concede you this point, I enabled Cloudflare no my side. I've read a lot of criticism of Cloudflare here on Lemmy itself, but it seems to be the lesser evil.

They can accept incoming connections from IPV6 trough Cloudflare's proxy, but the underlying server isn't ipv6 capable:

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)

lemmy.ml seems to have the same problem

Cloudflare is a few clicks away, but I don't wanna use IPV4, I want the world to move forward
