Followed this article and used the "You manage your domain" method to add a CNAME record at AWS Route 53, yet it is not working at Chromium browsers, receiving a Cloudflare DNS 1001 error, but works at Firefox. Here is the domain and the DO app domain, http://test.boost-art.net/ , https://ultraman-shot-telegram-bot-y63v9.ondigitalocean.app/
Found a similar issue here yet without solution, https://community.cloudflare.com/t/error-1001-dns-resolution-error/318802
It seems that digitalocean app domain uses cloudflare cdn, but cloudflare cdn don't accept cname when the ns is not hosted by cloudflare. However it only happens at Chromium browsers, Firefox treats the cname operation fine. Cloudflare may be the root reason. Could I change the digitalocean app domain to not use cloudflare cdn?
