Anyone seen this.  I've reviewed the cert and it looks to be valid:

Updates are not being deployed to machines.

In C:\windows\ccm\logs there is a UpdatesDeployment.log file.

In the file we are getting the following error:  Failed to get update (Site_9B83D81F-9241-4BB8-84E6-0EECC1872B54/SUM_344531f5-81fc-4323-ba43-ab612fd5fe60) Article Id, error = 0x87d00215
