Error accessing or checking UrBackup's internal database

Hi everyone, this morning I was checking my UrBackup Server and I got this message

I am running UrBackup version 2.3.8 under Windows Server 2016 Standard 64-bit on a 256G SSD (using only 26GB ) and 8GB RAM.

I didn’t know what to do next, so I decide to restart the computer (server) and now the message disappeared, hmm should I worried about it? I have a backup of the server, but everything seems to be fixed automatically … I also have the logs saved, but couldn’t see anything obvious … any suggestion is appreciate. I would like to know what should I do after getting this error, so maybe I could be proactive and prevent this for the future.

Thank you uroni (Martin) and all that help to make this amazing software.
