Docker Grafana - VPN to MSSQL not connecting [closed]

I have a grafana container running on my linux server. I am trying to get a connection from Grafana to my MSSQL server which is on another network but VPN connected.

From the linux server running docker, I am able to ping the MSSQL server via IP and DNS name. I can also ping the linux server from the MSSQL server.

However, when i use sqlcmd -S MySQLServerName -U Username - P Password, there is no connection and it times out.

I have even done a packet capture on my firewall and can see the ping commands moving back and forth, but no traffic at all when I issue the sqlcmd.

Any ideas?

Linux running Docker = 10.10.10.5MSSQL = 192.168.251.5Wireguard server between routing traffic.
