Re: NET::ERR_CERT_AUTHORITY_INVALID Error

Hi Zul,

Greetings.

Did you enable the Rule-set "HTTPS Scanning" (earlier known as SSL Scanner) in the MWG?

The error - NET::ERR_CERT_AUTHORITY_INVALID is displayed when the browser failed to validate the Issuer (or if the Root CA of the Issuer is not loaded in the certificate list)

Here the certificate Issuer is McAfee Web Gateway.

Please follow the attachment - Export Cert.PNG with steps to Export the certificate.

And import this in the client Cert list (Place in "Trusted Root Certification Authorities").

You can also push the certificate to all endpoints using Group Policy update.

Refer - https://community.mcafee.com/t5/Web-Gateway-Documents/Web-Gateway-Deploying-a-trusted-CA-to-your-Cli...

 

Regards,

Vineeth
