Topic pretty much says it...most sites work fine using my below set up, but some (Apple's app store) do not. I'm wondering if cert pinning is the issue? Since this set up is basically two separate sessions, I packet captured both. The side the I have control over gives me a TLS Record Layer Alert Close Notify. I am unable to decrypt the other side as the device in question is an iDevice and I can't capture the master secret. I've even tried to ACL certain sites to not bump, but they don't go through. Below is my complete setup. This is running the below: Squid Cache: Version 3.4.6 configure options: '--prefix=/opt' '--enable-icap-client' '--enable-ssl' '--enable-linux-netfilter' '--enable-follow-x-forwarded-for' '--with-large-files' '--sysconfdir=/opt/etc/squid' Any assistance with troubleshooting would be wonderful...thank you.
