IPv6 only - no seeds downloaded

Hello,

my YACY-instance is not able to load seeds on a IPv6 only environment.

My server runs on IPv6 only and Tayga NAT64 for IPv4 connectivity.

YACY is running inside a k3s environment.

YACY is behind an nginx proxy.

Has it to do with https://github.com/yacy/yacy_search_server/issues/708?

3

the initial seeds list is enumerated in defaults/yacy.network.freeworld.unit. Would it be possible, that none of these initial peers is ipv6?

Thanks for the hint. I am using NAT64. Outside the container I can curl/wget the IPv4 seeds via NAT64. But not inside the container…
