My IPV6 only server is unable to federate properly with lemmy.world

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
That is very possible. IPv6 only is still problematic. There are still loads of servers without or with broken IPv6 connectivity. You could put cloudflare on front of your server and get an IPv4 address that way.

Well, you see, it's only been around 20 years or so. We need another 20-40 years of "IPv6 is coming" reminders before people really take a look at it.
I don't like it either but the facts are the facts. Transitioning between technologies is always hard, especially if it isn't necessary. Nat works too well.
This surprises me since Cloudflare has AAAA records listed for
lemmy.world. Do you know your way aroundtcpdump? If so, it might be interesting to see what's happening with traffic to those addresses. My desktop doesn't have v6 right now (sigh) or I'd be testing that myself ...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
ipv6 only
