OS X Mavericks 10.9.2 / Chrome 33.0... / Safari 7.0.2
I am unable to log in to StackOverflow using Chrome or Safari. Clicking the "log in" link displays a login page UN-styled by CSS and where the "Login" button does not respond to mouse clicks. I am, however able to log in using FireFox, which I am using to post this question.
In Chrome I tried disabling all Extensions, but the faulty page display persisted.
Edit with Additional Information:
Opening the Developer Consoles while on the Login page [https://stackoverflow.com/users/login] in both Chrome and Safari, I am seeing certificate issues for cdn.sstatic.net resources:
Failed to load resource: net::ERR_INSECURE_RESPONSE(in Chrome)
Failed to load resource: The certificate for this server is invalid. You might be...(in Safari)
While I am able to reach cdn.sstatic.net in all browsers via http, I am blocked in Safari/Chrome when I try to access it via https:
The site's security certificate is not trusted!and
Safari can't verify the identify of the website "cdn.sstatic.net"
Safari show me that the certificate ("ssl4121.cloudflare.com") is for cloudflare.com whereas the link is for sstatic.net, thus throwing the error.
My Interim Solution
- Visit https://cdn.sstatic.net in Safari/Chrome
- Click "Proceed anyway" in Chrome
- Click "Show Certificate" in Safari, then select "Always Trust" in the "Trust: When using this certificate" dropdown.
Now, visiting the login page correctly displays the correct CSS and allows me to Log In (finally).
Feels like a bit of a hack, but it worked.
Certificate: Unknown Authority
I removed the certificate ("ssl4121.cloudflare.com") from my Keychain in Keychain Access in order to re-test this issue. The results were the same, with an unstyled and unusable Login page.
After I re-imported the certificate into Keychain Access, the message "This certificate was signed by an unknown authority" is displayed in red near the top. When I mark it again as "Trusted", that message disappears.
