Centralized Certificate Store (CCS) and IIS bindings

Hello,

I'm trying to set-up a centralized certificate store so I can host two URLs from my server "cawl.nau.edu" and payment.mpcer.nau.edu"  I installed and enabled the feature, created pfx fils for my certificates and imported them with the names "cawl.nau.ed.pfx" and "payment.mpcer.nau.edu.pfx".  When I open centralized certificated the both appear, but do not show any details.  When I try to bind them using the centralized store using the bindings manager, neither seems to be applied.  When trying to visit either site I get a "PR_CONNECT_RESET" error.  If I go  back into the bindings manager, I can choose SNI, unclick centralized store and then choose to bind the certificates in the SSL certificate drop down.  If I rebind in this manner the payment.mpcer.nau.edu site works fine, but cawl.nau.edu still produces the "PR_CONNECT_RESET_ERROR".  Can you tell what I am doing wrong?
