The method you’re attempting to use to determine if RMS is down may not work as intended. This address is not configured to respond to pings. To clarify, if rms.teltonika.lt is down, you can check by visiting websites such as Rms.teltonika.lt - Is Rms Down Right Now? or any similar alternative.
To reconnect your device, go to System → Cloud Solutions → RMS. There, you’ll find a button labeled “Reconnect.” Simply click on it to start the reconnection process manually. Your device should then be connected.
I noticed that you have multiple devices connected. Are other devices experiencing the same issues, or is it only this particular device? If this only device affected, please check if it has internet connection, and try rebooting then.
