I HAD a perfectly running NextCloud server up and running on my raspberry.
I mainly used it for automaticly upload photos from my android phone and as a general storage of various documents.
All of a sudden I noticed that my client couldn’t upload new photos.
Checked status on the server and i says:
“Nextcloud check error”
“MariaDB service down”
As not beeing a Linux guru I have no clue what to do…
Is it that Nextcloud is to complex for me and I should use Dropbox or similar instead ?
But I really prefer to store my files on my own servers…
You don’t have to be a linux guru to start with. However, if you manage your own server, you should be open to learn some things and don’t expect to set it up once and running forever. So you will become some sort of linux guru
Try to find out why your database is not running any more and try to restart it.
