Question owner

Thanks for the links but nothing of them made any changes. I dont have a security Programm so that cant be the Problem. And the flash player should not be a Problem. I only have the Problem with sides where i was logged in. So any other suggestions?

Thank you for sharing the YouTube site certificate. It was signed by:

Cisco Umbrella Secondary SubCA fra-SG

Which is associated with OpenDNS.

Do you use OpenDNS as a home or business filtering service? I think they are pretty good with their certs, so I'm not sure why you aren't getting their page (which probably says something like you are not supposed to be watching videos, get back to work).
