I tried to configure the RMS to the device with my RUT200 and the serial number of the modem.
Since this process was acknowledged with an error, I tried to link it to another account.
As a result, the device can no longer be configured with the same serial number.
If this is the cause, could you help me?
I have taken the liberty of attaching the two screenshots of my problem.
I will be happy to send you the troubleshooting file as soon as you give me a private answer.
Firstly, I want to remind you not to share sensitive information such as device serial number and MAC address on public forums.
Regarding RMS:
If you wish to register a device to another account, you must first unregister it from the current account.
The ‘Error: Failed to resolve hostname’ message is most likely related to your device not having an internet connection. To check this, log in to your device via the CLI and execute the command ping 8.8.8.8. If it does not ping, it indicates that your RUT200 does not have internet access.
