All I really have to go on is those errors com.apple.WebKit.Networking is logging which apparently points to a specific thing it’s missing called “forward transport security”. Only the peek at step1 seems to make it as far as any of squid’s logs.

No other browsers affected that I can find, not even mobile Safari. The sites that do and don’t fail seems random too.

Fine: instagram.com, getpocket.com, youtube.com

Not fine: httpbin.org, news.ycombinator.com, basecamp.com, wikipedia.org, dribbble.com, icloud.com, vimeo.com, reddit.com
