Installing Manual Wildcard Cert renewal on IIS

My domain is:

My web server is (include version): IIS 10

The operating system my web server runs on is (include version): Windows 10

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I renewed my certificate manually (via a virtualbox linux instance) and now want to renew the installed certificate on my IIS Server (also used for email) how do I update the existing certificate? I have tried going thru IIS and install or renewing with the pfx file and it doesn’t seem to do anything.

Because * doesn’t work with, but you should have a https binding with

Yeah I found that out (missing a little too late after creating the initial certificate. I have kind of worked around via some redirection on my website but it is a royal pain.

Turned out I copied the old pfx file that I created the first time I generated the certificate not the new one I just created with openssl (was pulling from the wrong directory). Which is why nothing was happening when I installed it since it was already installed. So user error.
