Made the purchase of a domain in a Brazilian company called UOL (Universo Online). Once the domain has been registered, it came with the following standard DNS:
Nameserver: ns1.dominios.uol.com.br
Nameserver: ns2.dominios.uol.com.br
Nameserver: ns3.dominios.uol.com.br
I went into my hosting server and got the DNS server for me to upgrade in the field. The DNS of the server hosting is:

Went on the control panel of the company that bought the domain (UOL), removed the default DNS (ns1.dominios.uol.com.br, ns2 ... ns3 ...) and I upgraded to DNS of my webhost:

The company gave me a deadline 24-48 hours for DNS propagation.
I decided to enter the "intoDNS" (www.intodns.com) to check the situation and noticed that an error appears, see:

Is something wrong? Or is the DNS has not yet been propagated and I just wait?
