No access to website

I can’t gain access to website. Cloudflare is the confirmed host however it can’t be found when I log into the account.

What is the site?

Quick check and it looks like you are part of a multi user account, select your email in the upper left of the screen, toggle to the other account. Is the site listed the one you are looking for? It looks like the nameserver change has not yet propagated. How long ago were they changed at the registrar?
