If you have a client that connects to RCStream https://wikitech.wikimedia.org/wiki/RCStream, please take a moment to make sure that you are using a secure connection. Are you connecting to ' http://stream.wikimedia.org/rc' or '//stream.wikimedia.org/rc'? If so, the only thing you need to change is the URL scheme, replacing any http: and protocol-relative URLs with HTTPS (that is, ' https://stream.wikimedia.org/rc').
