@AKirtesh if a Saas uses Cloudflare, i don't use it.
most platforms uses cloudflare to shield & speed-up things but unfortunately, to login/singup might take forever.
also sluggish on navigation.
@RoseMarvelous4 don't stress yourself you need to configure the cpanel main domain to listen the external hosting platform ip where you will run your nextjs project there, and configure another A domain as the mail domain that listen to your current hosing ip i.e the cpanel.
it's very easy.
