I added my site to cloudflare Two months ago. At first, as soon as I added the cloudflare DNS to my hosting, everything worked correctly and the site was immediately reachable from all devices. Then for a week I did some tests, I removed the cloudflare DNS from my site and added the DNS from my Aruba hosting.
After a week, I added the cloudflare DNS and the site was no longer reachable after half an hour. I waited up to three hours for the DNS to propagate but the site was still unreachable, at that point I added the DNS from my Aruba Hosting
An hour ago I tried again to enter Cloudflare DNS and the site becomes unreachable again with these errors DNS_PROBE_FINISHED_NXDOMAIN
ERR_NAME_NOT_RESOLVED
Going to https://dnschecker.org/
There are no errors and DNS propagation occurs correctly
Is it possible that there is no solution?
