Hi Manuel,

As the issue is now resolved, can you mark this post as the solution?

To summarise the issue, it was related to how the network/environment was set up. The core issue was the device's were unable to access the DMA via the Agent -> Profiles List &/or through enrollment URL.

Regards,

I encountered similar problem with some MobiControl server(s) about 12-18 months ago.  For now, I could not recall exactly how the problem was resolved.  Might be able to find some written record/email(s).

Anyway, could you please provide more information related to your case:

- Have you ever successfully enrolled any Android-Enterprise on THIS MobiControl server?  With this v15.3.1.1151 or with which earlier version(s)?

- Was this MobiControl server upgraded from any earlier MobiControl version recently?  If so, from which version.

- Do you have any problem enrolling any AE device for devices of othe brand or of a different device model?

 Have you ever successfully enrolled any Android-Enterprise on THIS MobiControl server?  With this v15.3.1.1151 or with which earlier version(s)?

• Yes, i enrolled some of the Zebra MC93 devices with the Google Managed account on an older MobiControl version 15.2.2.1077.
• Maybe the update should be the reason for the issue.
• I have no other devices for the test, so i can not answer this question.

Hi Manuel,

Thank you for posting in SOTI Central.

Can you confirm that the Device can communicate on port 443 with your DMA Address?

Usually, this is the MS Address and can be found in MCAdmin -> Deployment Server -> Device Management Address.

Yes i can confirm that the Device can communicate on port 443 with our DMA Address.

Hi Manuel,

If you go into your App Policy and click the following, do you see any errors?

Can you also navigate to your "License Information" section in the Legacy View and also "Update", does it show any errors?

Also no errors in our license informations.

Hi Manuel,

Download this app (https://play.google.com/store/apps/details?id=com.nosari20.connectivitytest) and perform a connectivity test on your Device's Network. This will check the various Google Endpoints for connectivity.

On top of the above, are you able to navigate to your Enrollment URL within your Device's browser?

Hi Manuel,

did you recently update the license key in your MC environment which was previously assigned to another MC environment?

Hi Manuel,

did you recently update the license key in your MC environment which was previously assigned to another MC environment?

Hi Simon, yes the license key is the correct one. It shows also the right number of the bought licenses.
