As per my previous post:

In your MariaDB settings, the "bind-address=" is the one
being used by MariaDB, instead of the "bind-address=::", because of
the order it reads the config files.  The last one read is the one
that gets used.  So the simple thing to do is just to comment out the
"bind-address=" line in the
/etc/mysql/mariadb.conf.d/50-server.cnf file by putting a # at the
start of the line.  Then restart MariaDB:

sudo systemctl restart mariadb
