Hey Derek, I'm checking on this...
Looks like an Apple device networking error. My guess is that the device and the MA client is making an HTTPS/SSL connection
back to internal network and to the Mobile Admin Server, so the perimeter firewall is blocking the RDP connection. If this is the case, setup the Mobile Admin Proxy Service to facilitate connections like RDP. There is a SolarWinds KB article for setting up the MA Proxy Service.
Another possibility is that there is a DNS issue of some kind when trying to RDP to a hostname. On the RDP connection settings page, you could change the hostname to the IP address for the target system.
This problem may occur if there is Apple hardware along the way and can be caused by:
The error code refers to lost HTTP connections, which " usually indicates a highly overloaded server."
Another Possible fix is to restart your WiFi network connection (router restart)
do you use MAC cloning in your network?
