Does it happen to all HTTPS sites or any specific sites?

Hi,

as far as I know is: it happens to 2 Banks and 1 Airlines HTTPS site.
the others such as: facebook, google, youtube are working properly..

What I missed?

Thanks

Can you paste the entries in /var/log/squid/access log file for those specific banks and airlines?

48 10.100.100.15 TCP_MISS/301 389 GET http://www.garuda-indonesia.com/ - DIRECT/23.9.199.131 -
10.100.100.15 TCP_MISS/302 427 GET http://www.garuda-indonesia.com/ - DIRECT/23.9.199.131 -e

For troublshooting, change the entry

http_access deny all

to

http_access allow all

restart squid services.

Then check the websites (clearing the browser caches initially).

1435761965.690 12 10.100.100.15 TCP_MISS/302 420 GET http://www.garuda-indonesia.com/ - DIRECT/23.192.193.158 -
1435761965.779 6 10.100.100.15 TCP_MISS/301 317 GET http://www.garuda-indonesia.com/id/id/index.page - DIRECT/23.192.193.158 -
1435

no luck :-(

In squid.conf, use google's DNS for testing
dns_nameservers 8.8.4.4 8.8.8.8

(Note; check with http_access allow all)


Restart the squid service and check.

Hope, there is no firewall between the squid and the internet?

hi.. thanks
it resolved
I didnot do anything there.. I suspect it's ISP's problem..
