Hello,
The connections you are seeing are not to RMS, but to our FOTA server. This connection can occur every time you open the System -> Firmware -> Update firmware page if you have FOTA enabled as the device automatically checks if there is a newer firmware version on our Firmware Over The Air server. This can be disabled in System -> Firmware -> FOTA configuration. If after disabling you are still getting this unwanted connection, please let me know and I will look further into this issue.
