There's a survey link. Not sure it works as Cloudflare blocks me from accessing it. Oh the irony, having my opinion as EU citizen about an EU issue blocked by some silly US company.
It's the typical Cloudflare error where it tells you "Your browser sucks", not sure what a screenshot would help. :)
An error that shows Cloudflare's logo might not be a Cloudflare error but a website who has configured to block you. A screenshots shows what it might be.
