I recently added a fourth SSL "COMODO RSA" cert to my IIS10 Server 2016.
This is a dev server so we have one IP address and use host headers for a variety of domains in IIS.
If i inspect bindings they are tied to the correct certificate and also the checkbox for "Require Server Name Indication" is on.
When the site is accessed the browse has a ssl warning and if inspect the cert it says "Issued to: localhost" .
I used mmc to look at the servers Local Computer \ Personal \ Certificates and they are there. I have restarted iis , restarted the server, reissued cert and the issue persists.
What else can i check?
