[squid-users] ssl_crtd breaks after short time

Thu Jun 4 07:55:20 UTC 2015

Hi Amos,

I tried taking the config from James.. but I have the exact same issue 
as described below :(

After adding the extra logging from James config - I get this in access_log:
1433404085.331      0 10.47.171.244 TCP_DENIED/200 0 CONNECT 
216.58.209.106:443 - HIER_NONE/- -

which makes it seem as if squid does NOT see the url I'm trying to access :(

Remember all this worked with 3.4.12 :(

My config as it is now:
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
