Bom dia, acho que cheguei no meu limite gostaria da ajuda de vcs, tenho um servidor rodando squid com iptables a 5 anos sem problemas, mas na semana passada por problemas de hardware tivemos que reinstalar tudo, até ai sem problemas, aproveitamos e atualizamos as versões do squid para a 3.5.26, ai começou a peregrinação.
Vou explicar o cenário:
Uso squid com autenticação NTLM, sempre usei.
Depois de reinstalado os navegadores ficam com a mensagem "esperando pelo tunel de proxy" muitas vezes até dar timeout.
Percebi que isso acontece nos sites https.
Ja desativei a autenticação NTLM, criei acls por IP para todo passar direto e nada, ja deixei a conf do squid a mais limpa possivel e nada.

Se alguém puder dar uma luz, agradeço.
Abaixo meu squid .conf
