I installed a new PKI certificate on the MP and now our CMG clients have stopped communicating. Could this have something to do with internal domain not matching external? Should I use a wildcard cert instead? Will this affect internal communication if the wildcard doesn't match the internal domain?![76431-cmg.jpg][1] [1]: /api/attachments/76431-cmg.jpg?platform=QnA
Rebooted the SCCM server and now CMG is working. It has been rebooted before but this time it did the trick.
Thank you very much for the update and we're glad the problem is solved now.
Hi, @Stom, Aaron R
Thank you for posting in Microsoft Q&A forum.
We may check ClientLocation.log on client to see why client failed to communicate with MP.
