Error 521 Web server is down

I could not figure out what it is wrong to access the following website I receive this message: Error 521
Web server is down. Could you help me? Best regards

I have checked your account, but it’s working fine as far as I can tell.

I see you’re using Cloudflare’s nameservers. Are you sure your DNS configuration in Cloudflare is correct? Can you move the domain back to our nameservers (to fix it) or disable Cloudflare (so we can see the actual DNS config)?

you are right, I made a confusion with my IP. I read your tip about Google and figure out the right ip to point at cloudflare. Best regards
