Issues with Youtube

[GeneralWinter]

Hi all,

 

My users are all very concerned about an issue which has just popped up as we started the new term. Every time you try to access Youtube on one of our computers, or any device connected to our internet you just get a "Your connection isn't private" error. Usually this is easily subverted by just clicking advanced and then proceed, however upon doing this the page times out.

 

Any ideas would be appreciated as I'm stuck for ideas, the server clock was a few minutes and I know system time can cause the issue but when corrected nothing changed.

 

Thanks alot

What's the actual error shown when you click Advanced?

The error given after failing to proceed is: 'You cannot visit http://www.youtube.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later'

Sounds like it's been banned by a filter between you and them, ISP level if you don't know about it. They can't show an error because it's HTTPS, so they try to downgrade you to HTTP, which is blocked by HSTS which stops those kind of "attacks"

We had a similar error a while ago on multiple sites. We were a little late in implementing a new SSL certificate from our providers [HGfL (Herts) and Updata] Now have supplied with the certificate and deployment details normal service has been restored.
