Google Chrome Certificates

[joedurham1]

Hi all

 

I am having an issue with Google Chrome Certificates but only on one or two PCs. when i go to google.co.uk it comes up with the below error message:

 

Your connection is not private

 

Attackers Might be trying to steal your information from google.co.uk (for example, passwords, messages, or credit cards)

 

NET:ERR_CERT_AUTHORITY_INVALID

 

Google normally uses encryption to protect your information. When Google Chrome tried to connect to Google this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be Google, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.

 

You cannot visit Google right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

 

 

We are running CC4 with Windows 7 pro on the pcs

 

It has been like this for a couple of weeks now on this one machine so unless it is the world's longest attack I'm not sure what to do!

 

any help would be appreciated

do you use https inspection on smoothwall/lightspeed/other filtering system if so id guess those pcs dont have the appropriate certificate installed and are detecting the https filtering as a man in the middle attack (which technically it is) so blocking access

Seconding this - when we wake up our testing VM's from standby, we get the exact same error on Chrome when trying to access SSL sites like Facebook.

 

The system clock needs to be manually refreshed; sometimes rebooting doesn't do it, so we edit the Date & Time Settings in Windows (flipping it from Automatic to Off and back again) which clears the issue.

 

Would take a couple of seconds to try this remotely, just in case!

 

 

EDIT: Missed it by that much! Glad you got it working anyway
