Unable to block yahoo videos

Hi Engineers, Would you able to help me. I got a problem that we were unable to block videos inside yahoo. I already tried the application control and assign them on firewall policy but it wasn' t working. Any idea you can share? Regards Aaron

It appears Yahoo is broadcasting (at least some of its videos) via HTTPS. https://tv.yahoo.com/ The firewall is unable to look into the encrypted traffic, so you need to configure SSL inspection on the firewall and distribute the key to the trusted store of the web browsers on the client to avoid having warning messages popping up on the desktops.

Thanks for the reply Istvan but this link https://screen.yahoo.com is the one they' ve using. Unable to block I already tried it on what fortinet docs specified but no luck at all. Is there any other alternate solutions on it? Regards Aaron
