Thanks for the log!

Looks like we're trying (legitimately) to connect to clients1.google.com (various features in Chrome hit that URL), and the proxy is giving back an auth request (using basic auth). When we provide it, the proxy responds once again with a basic auth challenge and the process loops, which is what's causing the mess of connection attempts.

Adding proxy and auth folks to investigate. (I filtered the NetLog on clients1.google.com.)

I bet the elided 10 bytes are "Basic 0g==".

This is fixed on M71, but unfortunately the merge was rejected due to it existing prior to M69.
