SOLVED: An Error Occurred While Using SSL Configuration For Endpoint 0.0.0.0:443

One of our new clients had a server with error 7023 “An error occurred while using SSL configuration for endpoint 0.0.0.0:443”:

A quick investigation showed, this error has been occurring for months (likely years, but the logs had been overwritten), the server had no certificates at all in the PERSONAL store, and the server did not even have IIS installed.

It is certainly possible that something else, like Apache Web Server, had a binding, but we could not find it.

We think the most likely explanation was a cert that was installed and bound to 8006 and 443 had been removed from the CERTIFICATES > PERSONAL store by some previous IT tech and was now completely useless. So we decided to remove the references:

1. Launch a PowerShell as an Admnistrator
2. Type netsh http show sslcert to list the certificates in use on the server
3. If you are convinced these are garbage, remove the references to the dead certificates by typing:
   netsh http delete sslcert ipport=0.0.0.0:443
   and in our case, we also had to type
   netsh http delete sslcert ipport=0.0.0.0:8006
4. Type netsh http show sslcert to make sure the dead certificates are gone
5. Have a nice day
