What is the network configuration you’re supposed to input for the two to talk?
Doesn’t need to be specifics, just I need to wrap my head around the “config” so I can suggest to you how to confirm if the two are talking or if they are not talking.
You could be getting blocked by a number of things, ports not open, firewall blocking site, dns server blocking site, firewall content filtering, ISP filtering.
It all is quick to check, depending on if you are expected to know the network config for the two to talk.
