Issues accessing NC - SQLSTATE[HY000] [2002] No such file or directory

I don’t exactly know what I’m doing, but after some more searchig I came across this thread and decided to give it a go:

pi@nextcloudpi:~ $ systemctl start mariadb
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to start 'mariadb.service'.
Authenticating as: root

Honestly… no idea what this did/does but looking at the log, there are no new logs, like the ones above.
I probably need some more time to see if this really solved it.

If anyone can let me know what’s going on and what I did, would be great, thanks :laughing:
