Using the https:// URL for any of Puzzling.SE's chat rooms gives a security warning.

For example, in Firefox:
yellow "warning" icon on Secure lock-icon, and "not secure" detail
(Chrome isn't quite as in-your-face with it, but if you check the "View site information" $\require{enclose}\enclose{circle}{\sf{\tiny~\small i\tiny~}}$ it also tells you that "Your connection to this site is not fully secure".)

A quick check shows that amongst all the https:// Media objects there is one that is using the insecure http:// URL: http://cdn.sstatic.net/Sites/puzzling/img/bg_pattern.png?v=1 :
Page Info - Media tab

This background-overlay seems to be pulled in from the style sheet at

I assume this inclusion of an insecure element on a secure page is unintentional, so posting this as a . P.SE folks, if you can confirm seeing this as well, it might not be a bad idea to say so here.

See Network-wide HTTPS: It's time on main meta.

  1. (Planning required) chat.stackoverflow.com, chat.stackexchange.com, and chat.meta.stackexchange.com

It hasn't yet been completed.


Update 2017-05-22

stackoverflow.com is now https://. I've written up a lot of what it took to get here in a blog post. Next up is chat and then https-only cookies. We'll be ramping up HSTS max-age directives as we go. I'll continue to update this post as we deploy new bits.

As of today, this issue seems to be fixed. Huzzah!

Leaving this open (for now) in case the problem comes back, as I've seen nothing indicating it was intentionally fixed and nobody official has flagged it "complete".
