Problem connected MySQL

I have problem connected with my database server
I use QNAP storage
My Node Red installed in Docker
MariaDb in sytem Qnap
How config my flow mysql - IP adress
my flow answer me --> Error: connect ECONNREFUSED

MariaDB config
Server: via TCP/IP
Port: 3307
Server type: MariaDB
Server connection: SSL is not being used Documentation
Server version: 10.5.8-MariaDB-log - MariaDB Server
Protocol version: 10
User: root@localhost
Server charset: cp1252 West European (latin1)


I'm not even going to talk about the virtual network or Docker config here. Each of those introduce another level of complexity.

Many versions of MYSQL need additional configuration / security settings to allow a connection via TCP/IP from a different machine. A different machine is defined as a different IP address.

Also: Can you ping from one machine to the other?
