So I am assuming that these devices on the other networks did not check in correctly with the server. Is there a log or something on the client that we can go to that would help us find where the problem is coming from?
Yes, of course. It is the Host log
which is available individually on each Host. I can assume that these Hosts couldn't connect to your RU Server in the first place, and that should be reflected in the log. As for the reason why they couldn't connect - it could be a perimeter firewall on the Host side network, or it could be your RU Server computer (or perimeter firewall in the network) that blocked incoming connection to the RU Server. In other words this seems to be a network connectivity and/or security parameters issue.
We have some devices in hand and are at one of our other schools so we can test.
Really appreciate the help, we have been very pleased to have partnered with you guys for over 8 years!
Thank you for your kind words :)
P.S. Feel free to open a ticket
and send us your Host log in private if you are having difficulty figuring out the log's messages.
