Just to make sure we are talking about the same thing, I mentioned that you should enable the Service on your device in RMS. To do that, please follow these steps:
In RMS go to Management → General and select your RUT950.
Thank you for confirming this information. Could you please try unregistering and then registering your RUT950 to RMS to see if the issue persists? Thank you!
Could you please try adding your RUT950 to RMS one more time and check if the issue persists? If it does, I will send you a form to fill out so I can contact you privately.
The device was previously added to a different company, and when you tried to add it to your company, it attempted to connect to the other one. We have removed it from the previous company, so it should now connect to your RMS without any problems.
