I don’t think it is. Even if the nameservers were not working correctly (which I don’t think they are) should prevent you from setting up Cloudflare.
It’s taking too much time because you’re barking up the wrong tree. Like I said: this is not a hosting issue.
What’s “not working fine” about the nameserver?
And why does our nameserver working or not matter when you’re not going to use our nameservers anyways?
That’s normal. The only reliable indicator that your account is suspended is the client area and control panel saying so. The suspendeddomain.org page doesn’t only show when the domain is suspended.
