Hello,
Do you have valid credits?
Is RMS service and monitoring for your device enabled in RMS?
Does your device have correct time set in Services -> NTP -> General?
Could you to attach a troubleshoot file by editing your original question? Please, replicate the issue, then access router's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file from there. The logs in the file might provide more insight into the issue.
Best regards,
