MKR1310: device cannot be configured


I try to install a MKR1310 in the Cloud but I alway get the message:

This device cannot be configured
Executing command: exit status 1
Please try to:

Restart the Create Plugin on the computer.
Reconnect the device to the computer and make sure the power LED lights up.

Try again

The LED is lighting, reconnect, new install agent, nothing works. Arduino Lora Gatway is “online”.

What can I do to solve this issue?

Thanks for help, Alexander
