Hetzner Storage Box Borg Backup Broken Pipe

We kept getting a Connection to remote host is broken. Broken Pipe, e.g.

root@k1 ~ # borg create --remote-path=borg-1.4 --verbose ::'auto-{now}' /var/lib/docker/volumes/foo/
Creating archive at "sb1:borg/foo::auto-2026-01-13T11:12:21"
Connection to remote host is broken. Broken Pipe

The following helped:

apt install ethtool
ethtool -K ens3 gso off gro off tso off
