Hm, it looks like a bug in the firewall configuration. It was
disabling connection tracking for packets using port 123 (as is
normally needed on a public server), but that included also responses
from the NTS server, which is running in a container with a private
address, so the responses had a wrong source address.

It should be fixed now.

I still see some clients sending requests with increasing size up to
540 bytes, so I'm not sure if they don't like the shorter responses or
they are getting lost somewhere.
