Hello, Salafp ,
As we checked there is no unit with such ID created on our platform.
Have you removed your unit from the system?
First, you need to create a unit in the system.
More information on the link. – https://help.gurtam.space/en/article/configuring-and-deleting-a-unit
Then, in the unit settings, you can see the server address and port where you need to direct the device.
If after creating a unit and configuring the device, you have problems, please, write to us at firstname.lastname@example.org.
