Browser certificate Doesn't work for Google and some other websites
I cannot open Google, Youtube, other website in my browser. It shows certificate authentication error.
I changed it to be a trusted website. Now it looks like:

I have no idea what to do. I cannot google.
Other websites like facebook, yahoo and Gmail load correctly in the browser.
This post on google-chrome:
Your connection is not private
Attackers might be trying to steal your information from
www.google.co.in (for example, passwords, messages, or
credit cards). NET::ERR_CERT_AUTHORITY_INVALID
The message I get in chrome when I click advanced:
Hide Copy Code
www.google.co.in normally uses encryption to protect your
information. When Chrome tried to connect to www.google.co.in
this time, the website sent back unusual and incorrect
credentials. Either an attacker is trying to pretend
to be www.google.co.in, or a Wi-Fi sign-in screen has
interrupted the connection. Your information is still secure
because Chrome stopped the connection before any data was
exchanged.
You cannot visit www.google.co.in right now because the
website uses HSTS. Network errors and attacks are
usually temporary, so this page will probably work later.
Is it a problem with google servers, something in between, or a client side browser? Is there a workaround for the error?

TL; DR: Your operating system is too old and does not update certificates correctly. Update your operating system.
Long answer: I got this error also on a Fedora 17 PC using google-chrome version 49.0.2593.0 dev (64 bit).

stackoverflow.com normally uses encryption to protect your

You cannot visit stackoverflow.com right now because the
website sent scrambled credentials that Google Chrome
cannot process. Network errors and attacks are usually

Here's what chrome google has to say about the error:
https://support.google.com/chrome/answer/4454607
I tried to fix this with no effect:
Clearing the cache and cookies of chrome.
Uninstall google-chrome and re-install it.
do a sudo yum update to make sure everything is up to date.
Make sure there are no extra routers between my desktop and the internetmodem.
Logging out of stackoverflow from all devices, trying again.
Turn off all port forwards on the internal network router.
Rebooting the modem and restarting the computers.
Using a different separate internet connection through tethering.
Disabling all google-chrome extensions.
forcing a visit to the site with http://, not https://
Use the development branch unstable branch of google-chrome
Opening stackoverflow in incognito mode, and trying http:// and https://
Enabled stackoverflow as a trusted site.
Error when clicking the https: // button on the URL bar:
Your connection to stackoverflow.com is encrypted using a modern cipher suite.
The connection uses TLS 1.2
The connection is encrypted and authenticated using
CHACHA20_POLY1305 and uses ECDHE_ECDSA as the key
exchange mechanism.

Final solution that worked:
Wipe the entire operating system down to bare metal and then reconfigure the entire operating system from scratch, with the same operating system as before, with the same google-chrome version as before, then it let me in. Maybe it's a malicious horse trojan or viruses detected by chromium.
The operating system's certificate management system suffers from a tailgate shutdown.
