Device Offline Not available

I am starting the Udemy "Building IoT Projects with the Arduino IoT Cloud". My Arduino MKR1010 WiFi is seen as a Device in the Cloud, it is linked to a Thing. I cannot upload the associated sketch as the web editor says the device is not available. Looking at the device page, the device is shown as Offline.

I have been unable to find where or how to change the device status to available.

The forum members assistance to resolve this problem, would be most welcome. Thank you. John Hollis

Use the Arduino IDE.

No one I knows uses the Arduino Web Editor.

Thanks for the quick reply. I now have to work out how to connect to the Arduino IoT Cloud once I've created my sketch. My job for tomorrow. Thanks again John H.
