Problem Configuring Nameservers

I created a droplet in Digital Ocean and installed the Whm Cpanel,


I followed instructions in this tutorial

tecmint.com/install-cpanel-whm-in-rhel-centos

I configured in the Whm panel the nameservers






Then following the instructions in Digital Ocean site i configured the nameservers like this

digitalocean.com/community/tutorials/how-to-create-vanity-or-branded-nameservers-with-digitalocean-cloud-servers



In Goddady i configured the nameserves this way



And the domain in this way



The result is that i have a mess with my domains, just few sites are working and allthe others are offline, in my machine i can see new sites that y create with new domains pinting to ns1.example.info and ns2.example.info but in other computers i can't (i already cleaned cache and flush dns and also restart the modem)

In the most of the cases i get this screen



I can see some other sites in my machine but not en others.

- Removed -

I edit nameservers yesterday in the morning. I don't know because of my lack of experience if is just that i have to wait for propagation of if i really make a bad configuration.

 

Thanks for your reply, i'm working now with Cpanel and DO support representatives in order to solve the mess i did.
