If the default detection script was recently updated, restore the script file from a recent backup or from an IAG server that hosts the correct detection script.

Open Windows Internet Explorer.
On the Tools menu, click Internet Options.
On the Content tab, click Certificates.
On the Trusted Root Certification Authorities tab, review the certificates to verify that a valid Certification Authority certificate is installed. For example, if the SSL certificate is issued by Thawte, verify that the Thawte Server CA certificate or the Thawte Premium Server CA certificate is installed on the client computer.
