Unifi Server quit working

I have a Unifi server running on Vultr. All of the sudden I went to make some changes today and I was unable to connect through the web URL:8443. I am able to ssh into the server and it is still running. I’ve tried rebooting the server and restarting the unifi service. Both had no results. Appreciate any tips. I am running version 6.5.5 currently. Ubuntu 20.04 LTS x64

If you can’t get into it I would suggest reloading from backups.

If you don’t have a backup you could scp one from the autobackup store. Then try just a simple install over the top. I would use Glenn’s scripts to install the same version. I use his scripts all the time to deploy controllers.

Backup store path on my 22.04 controller
/usr/lib/unifi/data/backup/autobackup

Glenn’s Web url to scripts:

Hope this helps.

Thanks for the tips. I was able to get the backup as you said. I also noticed what I believe happened was my logs just keep filling up. I think that is what stopped my controller from working. My server was filled up to 136 GB. I cleared out the logs to free up space and it was filling quickly. I’m not sure why the logs are filling up.
