I had spent four hours or more with little sleep trying to figure out how to allow access from WordPress user through 172 IP group to Maria, which was a problem as I host a shirt store for myself and others until I finally stumbled onto the support button and found this fix, it really was a savior. I hadn't connected the dots it was an update issue, I thought it was an issue of a failed database.
I put my repository back to default, had a database failure message on the site again, rechecked for update and had one available.
After update, the site was back to working function so this was also a fix.
