MySQL runs on remote Windows VM.
VM is up and running, mysqld.exe too.
MySQL is while installation activated for TCP/IP access.
Port 3306 is in my.ini and in connectivity settings of MySQL.
Firewall opened while installation and freed in connectivity settings.
Connection test to IP succeed.
Test with powershell Test-Netconnection -ComputerName <IP> -Port 3306 fails.
Q: What can I try further to establish successful connection test?
Screenshot displays powershell with test, connectivity settings of MySQL and task manager. 
netstat -an|findstr 3306?
