I have been working for a couple of weeks diagnosing the error with my /CMApplicationCatalog where it reports "The web site cannot communicate with the server. This might be a temporary problem. Try again later to see if the problem has been corrected. If this problem continues, contact your help desk."
This is a single instance box with Config Manager and SQL residing together. I installed everything by the book for my environment. (But I'm here asking for help, so apparently that's not entirely true)
I have searched all through Technet, Google, and anything else I can find. I've identified the cause of my error, just not how to fix it. Looking at my IIS settings for /CMApplicationCatalogSvc under the Connection Strings, I changed the Encrypt=True to Encrypt=False and that fixed my /CMApplicationCatalog. However, every time a I reboot it reverts back to Encrypt=True thus breaking my /CMApplicationCatalog. Obviously, I'd prefer it to be encrypted. Now I'm hear, asking for guidance.
When I look at the certificate options for my SQL server I have 2 options. The first is "ConfigMgr SQL Server Identification Certificate" that is self signed (obviously that's my problem). The latter option is a cert signed by my CA that is trusted by my clients, but SQL will not start when I select that certificate.
How do I setup a signed cert with SQL?
