Qlik Sense Enterprise on Windows and Chrome 58+ SSL Certificates warnings: Your connection is not private

Google Chrome 58 and higher displays a “Your connection is not private” warning when accessing Qlik Sense Hub or QMC.

The same issue might also be seen for other non-Qlik-related HTTPS URLs.

Environment

Qlik Sense Enterprise on Windows

Resolution

The issue can be resolved differently depending on the Qlik Sense version and the certificate authority in use. A temporary solution can be to ignore the browser warning or to use another browser. Permanent solutions depend on the current version of Qlik Sense.

3^rd party certificates

Qlik Sense sites that use 3^rd party certificates, have to be updated by acquiring an updated certificate from the certificate provider. Please consult local IT team for more guidance on how to apply a certificate update.

Qlik Sense Standard self-signed certificates

Certificates self-signed by Qlik Sense do not contain the “Subject Alternative Name” attribute. A possible solution is to configure Google Chrome to allow certificates issued by local trust anchors that are missing the subjectAlternativeName, which can be done by setting HKEY_CURRENT_USER\Software\Policies\Google\Chrome\ EnableCommonNameFallbackForLocalAnchors= dword :1 in the Windows Registry.

Changes to the Windows registry can lead to severe system problems if not applied accurately.

See attached .reg file as a reference to applying EnableCommonNameFallbackForLocalAnchors in the Windows registry.

Cause

This issue is caused by Google Chrome 58 (and later) requiring the “Subject Alternative Name” attribute, including the “DNS Name” value. See Google Chrome issues 308330 as reference.
https://bugs.chromium.org/p/chromium/issues/detail?id=308330
RFC6125 (https://tools.ietf.org/html/rfc6125) definition of “Subject Alternative Name”;

   If a subjectAltName extension of type dNSName is present, that MUST
   be used as the identity. Otherwise, the (most specific) Common Name
   field in the Subject field of the certificate MUST be used. Although
   the use of the Common Name is existing practice, it is deprecated and
   Certification Authorities are encouraged to use the dNSName instead.

This is an example of a certificate that will work without issue in Chrome 58 or higher. Note the highlighted portions:
