Unable To Connect To Device when attempting to reprovision

I had sent a device to a friend as a learning/testing process. They were unable to successfully connect it to their network via the reprovisioning process and have sent it back to me for troubleshooting.

When I attempt to reprovision from two different phones and one tablet without success. I can see the Wifi network that it is broadcasting. However, while going through the reprovisioning process, the app says it has Connected and is getting device info. The app will sit at “Waiting for device online” before failing with “Unable To Connect To Device” after some time. I have tried following the suggestions here. The template name is only 14 characters long, fwiw.

This seems like something silly, but I’ve been stumped for a few hours. Thanks for any guidance.

Is the WiFi network broadcasting on 2.4 and 5GHz on the same SSID?
If so, then try setting-up an SSID that is 2.4GHz only and try connecting to that.

Have you made any changes, such as deleting/renaming the template that was originally used when you flashed the device?

I’m also a bit confused by your references to your friend’s setup.
Are they a part of your organisation?
Did they flash the device with new code then try to provision it, or did you do that?

Pete.
