Nameserver changed But website does not redirect

Hi! I successfully added a droplet, setup cent OS Web panel and linked my domain to the droplet. However, I want this domain to work as my custom nameserver so I followed the tutorial below: https://www.digitalocean.com/community/tutorials/how-to-create-vanity-or-branded-nameservers-with-digitalocean-cloud-servers

My domain is cliche.shop The custom nameservers are: ns1.cliche.shop ns2.cliche.shop

Now the problem is, if I issue an user from Cent OS Web PANEL and add a domain and change the domain’s nameservers to my custom nameservers, it just does not work. The following domain is added from an issued user from Cent OS Web Panel but it does not work: clichestuffs.com

I am really a noob and wanted to learn about setting up such servers therefore do not have idea at all on what went wrong.
