blocking facebook but getting "your connection is not private" page

[dirkdigs]

i would like to see the fortinet web filter blocking page when going to facebook but we are getting some invalid ssl certificate page 

it is blocking the page but i would prefer to see the fortinet page so we know that fortinet is the one blocking the page 

 i have applied a web filter profile and a ssh/ssl inspection profile to my policy . i have a feeling its a setting in the ssh/ssl policy tat is causing this .

it seems to have something to do wit the fortinet ssl proxy certificate that it is using .
