The article describes about the issue where the certificate check on Windows 11 fails with 'No cert' error.

When the users tries to access the PCS URL, we do not get a prompt for certificate to choose for either certificate check or certificate authentication.
It loops for a while and throws "No Cert" error.
Issue is applicable for following conditions:
