My server is connected via wifi to my home router. The server every now and then will not allow me to log in via ssh. There seems to be nothing wrong, the journalctl -u ssh doesn't show anything odd. The syslog shows wifi disconnects on a periodic basis but at first it didn't seem too important.
the output of the restart of ssh was this:
Oct 28 09:54:25 server1 systemd[1]: Stopped OpenBSD Secure Shell server.
Oct 28 09:54:25 server1 systemd[1]: ssh.service: Found left-over process 1776273 (sshd) in control group while starting unit. Ignoring.
Oct 28 09:54:25 server1 systemd[1]: This usually indicates unclean termination of a previous run, or service implementation deficiencies.
