Hi,
Thank you for posting in Microsoft Q&A forum.
Firstly, please re-enter your username and password. And also check with your company support for the website that you need to provide in the Management endpoint text box.
Then, we suggest accessing Microsoft Endpoint Manager admin center->Devices->Enroll device->Automatic Enrollment, and check if the MDM URLs are there. If not, click "Restore default MDM URLs" to see if we can get the URLs.
Meanwhile, as a reminder, please ensure the user we enter to do the enrollment has Intune license assigned.
Thanks for your time. Have a nice day!
Best regards,
Simon
