Thanks for any feedback you can provide!
My guess is that the ConnectionTester is telling you that it's connecting to the cloudgateway at <IP> over NATS (port 5100) in order to validate whether that cloudgateway has a connection to dataminer.services (internet).
This does not mean that the cloudgateway needs port 5100 to have open internet access, only that the ConnectionTester is connecting to that port.
