Hi together,

I have deleted one device in RMS as I could not establish a connection. I have realised that I accidentally chose the Wifi MAC instead of LAN MAC. Maybe this was the issue.

Nevertheless when I tried to re-add the device with the LAN MAC I get the error from the screenshot.

Probably the device with serial number has to be deleted entirely from the system. So I can add it again with the correct MAC.

Do you know help?

It is most likely that you have by mistake added another device to RMS with an incorrect MAC address, could you check if you have any other device that has this specific MAC? And if yes, then remove it

I have checked this. But this doesn't seem to be the problem. Before, when I tried to delete the device, it said that it is just being deleted when there's an internet connection. But as there is no internet connection possible, it seems to me that the device (with serial number) is still in the system and blocks re-adding it. Is it possible to delete the device completely from Teltonika side?
