reboot command not working from SSH

yt flag

Today I changed the DNS on my Ubuntu 20.04 server to 8.8.8.8/8.8.4.4, I then ran sudo reboot. The server did not actually restart and now trying to authenticate through SSH is met with a 5 minute hang. When I did finally get in, the system did not reboot. I am now trying to run reboot as the root user and running the reboot command results in the ssh terminal hanging for a few minutes and then seemingly nothing happens, no output nothing. 'who -b' returns the last boot time as several months ago.

Not sure what to do, I don't want to do a force shutdown and I would like to reboot the server to fix the ssh hang.

I should mention my DNS is not working. 'ping google.com' returns 'ping: google.com: Temporary failure in name resolution'

Any help would be appreciated.

systemd was not responding, reboot -f was able to get it restarted.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
