fbmac2

All lemmy instances that I looked at have this problem. I gave up and used cloudflare for a while, and now I have an IPV4 machine that use haproxy and an ssh tunnel to forward everything to my server. The AAAA record points directly to my server

I'm not happy with this setup, but my instance wasn't very useful without connecting to anything else

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.

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

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

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
