[squid-users] Trouble accessing outlook.com

[Danilo V]

Hello, I'm having trouble accessing *http://outlook.com
<http://outlook.com>* through Squid.
The browser returns: Unable to connect (ERR_TUNNEL_CONNECTION_FAILED).
This problem is intermittent, it means that at some times it's all right.
Everything else is normal. Requests without proxy are allways OK.
I also tested using a clean installation of squid 3.4.8
