Issues Intune and okta enrollment

Hi all,

I could use some help or guidance from someone who has experience with using Okta as IDP and Intune as MDM. 

The problem:

When going trough enrollment (COPE), the Intune login page shows up. When entering the email, it forwards to Okta as it should. But after verifying with Okta, you should get back to a Microsoft confirmation but instead it shows a page not found error. 

It used to work, nothing has changed as far as we know and the issue is present on devices ranging from Android 13 to 15, different brands but mostly Samsung. 

Apple and Windows enrollment work as expected, no issues there. 

I can't find any related logging details in Intune and lack the knowledge of Okta (will add a support ticket there as well). So i'm kind of lost as to what is happening. 

Where do I need to look for the return URL for example? There are multiple Azure enterprise apps but i'm not sure which one to check and don't want to mess to much with this. 

Thanks!
