I have backed up and imported databased and move website files over to Digital Ocean server but droplet IP http://157.245.93.238 keeps redirecting to /cgi-sys/defaultwebpage.cgi, how can I remove this and make my website index page visible?

Server is on CentOS using Cpanel & WHM.

Also when installing Cpanel/WHM it asked me for 2 name servers which I put as ns1.domain.com and ns2.domain.com did I do this correctly or do I need to put it as digital ocean’s default ones?
