Notice today that when opening the community site Chrome has a red X over the HTTPS connection. Says the site uses a weak security configuration (SHA-1 signatures) so your connection may not be private.
Not that anything here should be all that important. But interesting anyways.
No proxy on my side. The machine that showed this was a Ubuntu 14.04 machine.
I did log in from another machine and it did show normal. So obviously something with that particular machine. I will reinstall Chrome and see if that makes a difference.
The screenshot was from a 14.04 box as it happens! So either you have a newer Chrome version than me or its something to do with Ubuntu root certificates package. Might be worth checking ca-certificates package is up to date too
