@Mark Wright , From the error message, it shows that admin required your device to be managed. In "Device state", it shows unregistered. Here, we suggest to enroll this Android device into Intune and see if it is working.
As a reminder, I notice Ip address is in the picture. To protect the information in your environment, I suggest to hide this privacy information.
Thanks and have a nice day!
