The certificate’s Subject Name does not match what WAC is configured to use
WAC binds to the certificate using Subject Name, not SAN.
If your certificate’s subject is an email address (as in your example), WAC will not match it.
Example of your subject:
E=email address removed for privacy reasons CN=email address removed for privacy reasons
This is not valid for a WAC gateway certificate.
WAC requires:
CN=servergw.domain.com
Even if SAN contains DNS names, WAC still matches on Subject Name, not SAN.
Reissue the certificate with:
- CN = servergw.domain.com
- SAN = servergw.domain.com, servergw, etc.
Then run:
Import-Module "$env:ProgramFiles\WindowsAdminCenter\PowerShellModules\Microsoft.WindowsAdminCenter.Configuration" Set-WACCertificateSubjectName -SubjectName "servergw.domain.com"
