This can be either a proxy server, or the target host. What steps will reproduce the problem? This policy resulted in problems for deployments whose HTTP proxies intentionally failed certain https:// requests, since that necessitates inducing a failure during the CONNECT tunnel establishment. Chrome's algorithm for myIpAddress() favors returning the IP that would be used if we were to connect to the public internet, by executing the following ordered steps and short-circuiting once the first candidate IP is found: Note that when searching for candidate IP addresses, link-local and loopback addresses are skipped over.
