DNS/NS Set up

[rcschaff]

This is 100% a DNS issue.   You really need to contact the registar about the issue.

Good morning, I changed the registrar, made all the configurations on the domain configuring the ns1 and ns2 and I continue with the same problem, the ns in cwp did not solve me

If your nameserver are set to ns1.mifm.online and ns2.mifm.online, then it should be working.  The only thing I can think of, is that the .online extension does not have the capability of being used as nameservers.  Some extensions do not support Glue Records, and it's quite possible .online is one of them.   Which is why most people use .com/.net as nameserver domains.
