Running the latest version. I backed up, as done before on this same version and a few services didnt backup properly. So i tried again, same thing happened. Then after the second backup attempt, all services crashed. I then tried to restart. Now it boots straight into diagnostic mode. With a connected monitor to the server, it shows my start9 address on the tty1 page and thats it. The server login through another device shows diagnostic page. With a long list of errors, and says contact support at the bottom. please help, thank you!

Hey Vancity,
Without seeing the errors, there’s not much we can do. Please share a screenshot or provide some details about the errors you’re seeing.

I think the issue is fixed. I powered off and on the server, and it’s working now. Was able to back up fully as well!
