Hello,

I've recently managed to make my devices communicate with my local MobiControl server (On Premise) by configuring my firewall to allow the ports 444 (the one I use for the deployment server, my WebConsole is listening on port 443) and port 5494.

Now I want to enroll my devices from the Internet and when I try to enroll from my local network, the device is enrolled sucessfully but when I do it from the Internet, the enrollment fails.

The step where it fails is right after the SafetyNet step. In the logs of the Deployment Server Extensions, I get an error saying that a certain parameter "s" can't be null (System.IO.StringReader..ctor(String s)).

Is there a way to fix this problem?

The MobiControl product version I work on is 15.5.
