No rout to host

I set up my server (Ubuntu server 20.4. I have my ssh key working nicely. I set up Livepatch, and the next time I try to log in headless, I get "No route to host". So I look at netstat and here is what it showed for port 22

port 22: Locus Address Foreign Address state PID/Program home host

porto Tcp6 :::22 :::* LISTEN 831/sshd: Nsr/sbin

If you see an explanation that would be helpful
