This is HTTP 407 Proxy Authentication Required. Seen in a few support cases now. Normally completely unexpected and undetectable from other troubleshooting approaches.

SessionRuleSet.cs:

case 407:
/////////////////////////////
//
// HTTP 407: Proxy Authentication Required.
//
this.session["ui-backcolor"] = HTMLColourRed;
this.session["ui-color"] = "black";

this.session["X-ResponseAlertTextBox"] = "!HTTP 407: Proxy Authentication Required!";
this.session["X-ResponseCommentsRichTextboxText"] = "HTTP 407: Proxy Authentication Required" +
	Environment.NewLine +
	Environment.NewLine +
	"Seeing these in a trace when investigating Office 365 connectivity is a big indicator of an issue." +
	Environment.NewLine +
	Environment.NewLine +
	"Look to engage the network or security team who is responsible for the Proxy infrastructure and give them " +
	"the information from these HTTP 407 sessions to troubleshoot with."
	Environment.NewLine +
	Environment.NewLine +
	"Office365 traffic should be exempt from proxy authentication or better yet follow Microsoft's recommendation " +
	"to bypass the proxy for Office365 traffic.";
