This node is running with IPv6-only.
Since I did not have IPv4, I initially only commented the constraint
with IPv4 . But it was not enough.
Then I realised that pool.ntp.org doesn't include a AAAA record.
That is ntppool's decision.
I ended up by commenting the servers line and added several servers close
enough .
I posted my question on github [1] and someone advised me to rely on
"2.openbsd.pool.ntp.org"
Is it possible the default ntpd.conf file use something like
"servers openbsd.pool.ntp.org" and of course have openbsd.pool.ntp.org
looking for IPv6 nodes?
openbsd.pool.ntp.org won't help, that doesn't have AAAA records either.
Perhaps the usage of DNS64 + NAT64 could help.
