my first MYSQL server (no replies)

Hi, I'm giving MYSQL Community Server a go for the first time and plan to migrate a MSSQL database across once I've got the basics.

I seem to have a problem with connection but I'm not sure where to troubleshoot...I'f someone can point me in the right direction would be much appreciated.

Server side:
- Have a Debian 9.4 VM
- Have installed MYSQL server 5.7.21 on the VM from repos
- Have installed Workbench 6.3.8
- Can connect to the server locally via workbench
- added a user that I wish to connect with. In the limit to hosts field have added the IP of the client (not sure if this is what I'm meant to do though).

Client side:
- Have a win 10 client
- Have installed Workbench
- Have installed a MYSQL ODBC driver 5.3 ANSI
- Have made a new connection with the Hostname as the server IP and tried the Host name of the sever
- I have not changed the default port of 3306

When I try to connect I get the message 'Cannot Connect to Database Server'. I have read I need let set the allowable clients IP on the server but not entirely sure where I should do this.

What should I start to check?
Do I need to install a ODBC driver on the Debian VM?
