Hi.
I've tried as suggested by you and started with removing all device data from the cloud.
I' ve tried from the very beginning- add the NANO as new device.
And Cloud was not able to configure my NANO.
So I purchased the next NANO 33 IOT and again , the IOT Cloud was not able to configure my board. Board have newest firmware version ( 1.5.0)
I've checked the WIFI and internet operation with my new NANO and - everything was ok.
So where is the problem?
