Hey Colin,

Thanks for checking in on this report.

It's a standard SSH config, without manual config changes.

root@debian13:~# grep -i listen /etc/ssh/sshd_config
#ListenAddress 0.0.0.0
#ListenAddress ::

root@debian13:~# systemctl reload ssh
Job for ssh.service failed because the control process exited with error
code.
See "systemctl status ssh.service" and "journalctl -xeu ssh.service" for
details.

To give more context: This is a LXC container running Debian 13 on a Debian
12 host. Maybe this is an important information needed in this context.

I just tried to reproduce the same reload error on another LXC container
which was upgraded from Debian 12 to 13 (Host running Debian 12) but here I
did not get any errors.

I have to dig deeper into this to find the differences.
