> *Need to adjust which part of the settings?* If that connection is really trying to connect to 127.0.0.1:3129 from Squid point of view, then your interception setup is probably deficient. Intercepted to-port 443 connections should be seen by Squid as going to port 443 (while being received at Squid port 3129). Interception is not (or should not be) just port redirection. This has nothing to do with Squid configuration though. Once you fix interception (or if you refuse to fix it), if Squid is denying access, then you should adjust your http_access rules. Your rules must allow fake CONNECT request that represent intercepted HTTPS connections. For example, the above TCP_DENIED line is probably logged because your current interception setup triggers this (correct) rule: > # Deny CONNECT to other than secure SSL ports > http_access deny CONNECT !SSL_ports And yes, it might have "worked" in the past because earlier Squids were doing fewer checks that they should be doing.
