No connection could be made because the target machine actively refused it

Hi

I have the following setup Cluster in a Box (Ubuntu VM run inside Hyper V- Network Default switch).
From the Host(Win 10) im able to open VMIPAddres:8080 singlestore studio properly. When i try to connect to port 3306 using MySql.Data.MySqlClient; i get the following error “No connection could be made because the target machine actively refused it.”. I checked the port on the linuxVM, 3306 is open and listening.
I tried the same scenario using bridged network on VMBox and i get the same msg.
Any idea how can i overcome this issue?

Update
Using the memsql-admin tool changed the bindAddress, and now it works
