I’ve solved the issue. The Issue seems to stem form the MariaDB server. It looks like the password or something else expired and the solve is to root into MariaDB and reset the password the same as it was before.

Logging in as root on the MariaDB server

UPDATE mysql.user SET authentication_string = PASSWORD('same_password_as_before')
WHERE User = 'nextcloud' AND Host = 'localhost';
FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud' IDENTIFIED BY 'same_password_as_before';
exit;
