Hi everyone
Anyone have seen this issue before? It all started in february. More than 5k Android tablet have this error at check-in (logs mobicontrol) now.
Deployment Server error (Failed to retrieve and issue Client Certificate. Device may not be able to communicate on subsequent connections.)
![]()
The enrollment time (in the Information tab) for this tablet is 2015-10-20.
If we go to Certificates tab in Mobicontrol, we actually see that the certificate will expire in 2 months (April).
![]()
The thing is that we checked all our deployment server certificate and the expire date is in 2030 same as the Mobicontrol Root.

We are on the 13.4.0.5519 version
