PROXY - after blocking port 80 and 443 some sites are down

Hi as the topic… I am fully using proxy (authentication method: Windows Active Directory (samba), clamv, url filter itd.) After blocking ports 80 and 443, some sites are down (max 20%). no matter if they are https or http. I’ve run out of ideas … can anyone help ? [321]
