There's a resolution issue.

Prerequisites

  • Register vCenter Server with NSX Manager and deploy the NSX Controller cluster.
  • Verify that a reverse DNS lookup returns a fully qualified domain name when queried with the IP address of NSX Manager.
  • Verify that hosts can resolve the DNS name of vCenter Server.

As above, looks like a name resolution issue...

Dear Diego,

1.Register vCenter Server with NSX Manager and deploy the NSX Controller cluster (ok)

2.Verify that a reverse DNS lookup returns a fully qualified domain name when queried with the IP address of NSX Manager:

How can I nslookup in nsx machine ? Which is the right coommand?

3. If I try to my windows Pc, nslookup gives me the right results. He resolve the NSX /VC/HOSTS dns name and reverse.

I try to print nslookup in the 1st Host to ,for example, nsx but it doesn't respond. If I try to ping the nsx ip , resolve it. How can I fix that?

You can do the Name Resolution via the following command inside the NSX Machine. Do it in the Privileged Mode (run Enable before executing this command)

dnslookup serverFQDN
