I get this on my exit: "Auto-discovered IPv6 address [2a00:da00:f460:f800::1]:443 has not been found reachable"

As far as firewall is concerned it is reachable.   I can see the control port web page using Ipv6 address, and SSH into my odd SSH port using IPv6.   IPv6 is working and routing 100 % correctly.  IPv6 exits seem quite popular.

ORport [2axx:dxxx:f460:f809::2]:443

Somehow Tor does not see it, well it sees it to test the port but then says not reachable, but no access within TOR?

(Linux 6.8.0-10...)   Tor 0.4.9.5 (recommended)
