Dear Sbabu,

As per your previous email, I will follow the suggested steps. However, it is not feasible to communicate this workaround to all 300 users. Users are questioning why the issue is specific to Chrome while other browsers work fine.

If any changes require in your FortiGate firmware end please do as soon as possible.

Could you please provide a permanent solution for this Chrome-related issue at the earliest?

Thank you for your assistance.

Best regards,
Jagabandhu

As I know the whole point of portal detection (chrome uses http://www.gstatic.com/generate_204 ) introduced by modern browsers was to detect and silently redirect the users to the portal page before they try to reach a site that is using https. Redirecting an https page is not possible without using deep inspection (impossible for guests/unmanaged end users). I'm not sure why chrome choose to change this behavior but I guess it will be temporary.
