gov.uk - Invalid Certificate

[Tesla]

Anyone getting an invalid certificate message from chrome (or any browser) when visiting the gov.uk site? Colleague has been unable to get onto it for two days with this error (at home and on site)

 

any ideas?

 

Date and time are correct.... and no weird chrome extensions.

Nope, all working fine for me from Chrome. Have you checked all the certificates in the certification path are correct

works OK for me with

 

Firefox 51.0.1

IE 11.0.9600

Chrome 57.0.2987.133

Already checked... (mentioned in OP) ha

Might be outdated CA-Root trusted certificate on the client?

We've always had issues with gov.uk sites on our smoothwall box and have marked most as certificate exceptions.

We had this issue, we had to update the root certificate authorities on the smoothwall and that fixed the issue.

Windows had updates.... it worked after they were applied...

 

(complicated, but i'm not in charge of the laptop with regards to updates anti virus etc)

Might be related to the Chrome V58 upgrade and trusted certificate issue doing the rounds? There are fixes for Sophos, smoothwall and others around if needed. What Gateway/filter are you using?
