My website is not reached

Cloudflare nameservers used.
DNSSEC not being used.
SSL ok.
No redirect issue so far.
It works fine from my end both www and non-www.

May I ask have you tried using a different Web browser, or tried clearing your Web browser cache?
How about using a Private window (Incognito mode) or a VPN connection if possible?
Is it the same behaviour on your mobile phone (4G LTE, mobile data, cellular)?
