SQuid - TCP_MISS/503

[pereira285]

Boa tarde

Trabalho com o squid a bastante tempo e estou tendo problemas apos ter uma atualização no servidor de e-mail Zimbra que nos fornece serviço.
Apresenta erro ERR_TUNNEL_CONNECTION_FAILED e no Log apresenta TCP_MISS/503.

Caso alguém consiga me ajudar serei muito grato.

Desde ja agradeço
André Pereira

Boa tarde andr3.ribeiro

Cheguei a verificar as configurações do squid, porem onde ja esta configurado fica no /usr/local/pkg/squid.inc;
Todas as configs estão batendo.
E o mais estranho é que quando eu limpo o cache do navegador ele funciona por alguns instantes e depois para novamente.

Teria mais alguma dica?

Grato.

já colocou seu squid para não fazer cache no seu squid?

[andr3.ribeiro]

TCP_MISS/503 significa que foi buscado o endereço no cache.
Manda um print aí das suas confs de cache!

@jvicente:

adicione seu dominio ou o endereço do seu webmail para não fazer cache.
