W10 modern certificate enrollment : missing user agent

W10 modern certificate enrollment : missing user agent

Hi,

 

I'm trying to enroll W10 tablets with certificates enrollment.

I'm familiar with the process as I did it several times already, but this time, it won't get through.

I did everything by the book, generated all the needed certificates, prepared the mobicontrol server, and generated the WICD package for the tablets, but when looking at the DSE log, I see this :

 

[2019-06-03 13:30:32.171] ERROR [] (90): Enrollment failure: Client Info is missing User Agent.
[2019-06-03 13:30:32.171] ERROR [] (90):

****************************************

I checked the provisionning diagnostics provider event log on the device, everything looks fine except the provisioning failed at the end, so the device package looks fine (otherwise I have some more explicit messages).

The server is on SOTI Cloud, latest 14.3.3

Talks to someone ?

Thank you

Hi,

 

Thanks for your answer, I already opened a case @ EU support, just forgot to update here.

Fact is, my problems were only related to one device, other devices from same model didn't have the issue.

 

At first the problematic device didn't show up on the console at all.

Then I reset the device, and it did show up on the console but remained desperately offline.

I then noticed that the agent didn't download/install.

Then after several hours, the agent installed and it worked. Funny thing is... I did nothing to make it work.

 

Anyway, as the production devices don't have the issue, I'll put that on the mysteries in the universe that remain to be solved.

Hello Laurent,

In order to provide you with a solution to this i believe opening a case would be the best route to take.


You can open a new case using the link provided below:
