Lost access to Maria DB in Lightsail

Today i tried to enter my Maria databasers with DBeaver on my three Lightsail instances. The setup was done a few month ago and have worked without any problem

DBeaver failed. Error: Could not connect to 127.0.0.1:47610 : unexpected end of stream, read 0 bytes from 4 (socket was closed by server) unexpected end of stream, read 0 bytes from 4 (socket was closed by server)

So i tried again from CLI, MobaXterm:

r> mysql -u root -p Enter password: ERROR 2002 (HY000): Can't connect to local server through socket '/opt/bitnami/mariadb/tmp/mysql.sock' (111) VPS Main Server>

Then i tried from Lightsails own connection: mysql -u root -p Enter password: ERROR 2002 (HY000): Can't connect to local server through socket '/opt/bitnami/mariadb/tmp /mysql.sock' (111) VPS Main Server>
