So it is not your site which is behind Cloudflare, but your customer is using Cloudflare’s nameservers?

Can your customer provide you with a screenshot of the error and could he try to check to what your domain name actually resolves for him?

Thats not a DNS issue and not related to 1.1.1.1

Cloudflare cant reach your server. You need to check why. Your server is possibly down or prevents Cloudflare from reaching it.
