Unable to enroll Windows Phone Devices to SCCM Hibrid

[dyg]

Hi,

Since last week we are unable to enroll Windows Phone devices to our SCCM hibrid Intune environment.

It gets this error: "Confirm that you are using the correct sign-in information"

Also i get prompted to manually enter the MDM server name

I checked that we have the CNAME DNS entries explained in these links

With Android devices we don't have any problem, we can enroll it.

Any sugestions?

Thanks and regards
