Currently bought a domain and am having hard time

[Kingstonedu]

Hello there I currently bought a domain to use it to redirect to certain URL and after changing to different URLs in an event of testing I started getting this error "

This site can’t be reached​

Check if there is a typo in mysitedomain.​

NS_PROBE_FINISHED_NXDOMAIN"
I tried changing nameservers to cloudflare's with no success, I am using Namecheap. Any help will be appreciated

What do you mean by "no success"? What did you try to do after you changed the NS?

Cloudflare's NS could not work on the domain I don't know wether it's because of inaccurate ipv6 or cname or A record

What did you try to do after you changed the NS?

I was trying to get free SSL provision from cloudflare
