Environment

VMware NSX 4.1.0 and later

Cause

In 4.1.0, a check was added which requires an FQDN for NSX Managers using CA signed certificates for their API service.  This ensures that when a remote node returns its bundle back to the manager via an API request, the SSL request is validated correctly.

Resolution

Customer to define NSX Manager A and PTR records on their DNS servers.

Workaround
Manually collect support bundles via CLI with the following command:  get support-bundle <file>

Additional Information

Impact/Risks
If DNS entries are not defined correctly the support bundle collection will fail from NSX UI.
