Answer 1

Have you updated the binding on the website?

Answer 2

What bindings do you have specified? Do you have multiple web sites on this server? Are you sure that you are hitting the correct site name and IP? Any load balancers involved?

Check the cert in the IIS manager.

Download the Digicert utility to the server and check it locally.

Then run the tool on another machine to check the cert.

If you still get the wrong cert, browse a bogus url, https://sitename/xxxxxxxxxxxxxxx.htm

Then check your IIS log and look for a 404 entry for xxxxxxxxxx.htm. That will verify that the request is being routed to the correct web site.
