Windows Admin Center v2.4 will not use SAN Cert

Hello, We've noticed an issue with the new Windows Admin Center Modernized Gateway (v2.4) and SAN certificates, at least in our environment. All of our servers get an autoenroll computer certificate...

    No problem rmoat!

    Unfortunately it seems there is not much option than wait that the next build brought back the ability to update the certificates again. For now would you mind to leave the thread as resolved?

    Regards!

Thank you luchete.

Yeah, the SAN cert(s) were installed in the "Personal" store. It looks like the New-WebBinding cmdlets don't exist, and I'm guessing they are only installed if IIS is installed. Unfortunately, WAC v2 doesn't use IIS anymore.

I tried to generate many different certificates, with various certificate templates. Even one that was similar to the Computer AutoEnroll certificate template, but I just manually fill in the Common Name and DNS (Subject Alternative Name), and both use nearly all of the same cert template settings, and all I get is the "Connection Closed" error when trying to access the website.

Since this will be used internal only, it's not really that big of a deal. It would be nice if the next build brought back the ability to update the certificate within the actual website itself, instead of running the installer each time or using the Set-WacCertificateSubjectName -Thumbprint <certificate thumbprint>.
