PfSense+Squid Proxy=Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED) - https ONLY

dpessanha

Hi all!

I'm new to the pfSense world, so I'll assume that the problem can be my n00bness.
I have a machine with pfSense and Squid Proxy and my network machines are pointing to this machine as the GW. The proxy is working as a charm to all http pages, but the https pages show this error in Google Chrome (the IE doesn't show anything…): Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED). Ok. I give a F5 and the page loads as if nothing has ever happened. This problem doesn't occour every time I try to load a https page, but its enough to be a headache.

I know this is my fault in some rule, but I could not guess how to solve this problem. Can anyone help me?

Thanks in advance!

PS.: Sorry if I'm in the wrong place in the forum, but I'm new and n00b here too!

When googeling for this error it seems that not squid is the problem but the destination web server.
Which version of squid are you using ? If you use squid 2.7 try with newer squid3 version.

and if you are using squid3 then set the option "IPv4 first".

Hi, Nachtfalke!

Thanks a ton, man! It worked! The option in the pfSense GUI is in Services > Proxy Server > General > Resolv dns v4 first.

Thanks, man, thanks! =)

Thank you "Resolve dns v4 first" works!

I would also like to confirm this WORKS.

Thanks you!

hi everyone,

I enabled "Resolv dns v4 first" but it's always the same error : ERR_TUNNEL_CONNECTION_FAILED

I restarted Squid and Squidguard

Flush all web caches and flushdns on my PC

I'm blocked, any idea gentlemen ? :)
