That tells me either you have screwed up the CONNECT ACL definition. Or
the SSL_ports one.

I suspect that whatever you have done is making HTTPS no longer use port
443. That needs to be fixed.

Quite. The security protection intended by that rule is to deny the
identifiably bad things and let your custom rules that follow decide
what is allowed.

The required syntax is the default:

 acl SSL_Ports port 443
 acl CONNECT method CONNECT
 http_access deny CONNECT !SSL_Ports

Since you say that is not working, the problem is elsewhere and ACL
definition will not solve the breakage.

If you still need help, we will need to see what your squid.conf
contains currently. And if you are intercepting, the rules used for
doing that.
