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

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
