Sounds like you have a misconfiguration that should be fixed, rather than disabling IPv6 to work around it. > net.ipv6.conf.all.disable_ipv6 = 1 > > and run sysctl -p as root.

What is the new way of > disabling IPv6? That directory exists for me on all of my Debian 11 machines, so I guess you have something else wrong. Or maybe have already disabled IPv6 on the kernel command line (don't know if that removes the net.ipv6 sysfs tree as well). Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
