Upgraded to Squid3-dev, now traffic is being blocked

alltime

We have been using Squid for some time now, with no issues as a caching server. In an effort to intercept https traffic, we decided to give Squid3-dev a chance. Before even configuring https, we see that http is being blocked. Since we are not intercepting https, we can visit http sites just fine. Please see our configuration below. Does anything seem out of the norm?

No firewalls rules have changed. Simply an uninstall/install of squid3-dev.

Setup looks fine…
