As you advised me I have contacted the domain name registrar and I am waiting for their return.
but for the moment I have used another registrar for a new domain name.
Here is how I proceeded.
I filled out the form to add domain
then i went to register the nameserver on the platform of the domain name registrar
then i replaced the nameserver
I did these tasks yesterday morning; but until then when I check my server here is the result
Is this normal? did I fill in something wrong?
for my name to be propagated it must take more time?
