I manage my domain form Time4vps & I haved added the Cloudflare nameservers more than 24 hrs ago. However, It’s cannot be confirmed as it keeps the same checking process everytime with no results.
Domain: madystore. co
Nameservers:
hazel.ns.Cloudflare. com
yichun.ns.Cloudflare. com
You did not change nameservers, you only added two NS records to your host. You need to change the nameservers at your registrar instead. If it is unclear how to do that, you best contact your registrar.
