ERR_NAME_NOT_RESOLVED - server IP address not found

Hi,

I set up Cloudflare and changed the nameservers yesterday and am now having the following error message when I want to access the webiste:
“server IP address could not be found. Search Google for spring workout web ERR_NAME_NOT_RESOLVED”

The website is: infobetbonus.com

Perhaps someone could help with this?
Thank you!
Roy

Resolves for me -> sitemeer.com/#https://infobetbonus.com/

However I get an endless redirect, Community Tip - Fixing ERR TOO MANY REDIRECTS

Switch your SSL mode on Cloudflare to “Full strict” and make sure you have a proper certificate on your server.
