I can connect to an RMC4 with the Crestron Go app via VPN over a 5G T-Mobile cellular network.? I don't have any Crestron installations that I can test that are not VPN.? However, I did try this yesterday on a Vantage system where I tried to connect remotely to a system where port forwarding was in place and I could not get it to work over a celluar connection but when connected from a remote wifi network, it worked fine.? Definitely something fishy here.
