Creating a workload domain by importing an existing vCenter fails with the error "Error in configuring VLAN backed transport node collections"

Products

• VMware Cloud Foundation

Issue/Introduction

• The "Create NSX transport node collection" task fails for a Brownfield imported environment.
• The import fails at the "Create NSX transport node collection stage" with error "Error in configuring VLAN backed transport node collections" 
• In the workload domain's NSX Manager, expand System > Fabric > Hosts > the listed cluster, and the status displays "Installation Failed."
• ESXi nsxcli.log has entries like below:
  

  <TIMESTAMP> <ID> cli.server.cli_command_service INFO {0} CMD: join management-plane <FQDN> thumbprint <thumbprint> token <token-obfuscated> node-uuid <UUID> validate-manager-cert
  <TIMESTAMP> <ID> cli.commands.host_shared.register INFO Node registration failed, rc=28: curl_wrapper: (28) Failed to connect to <FQDN> port <PORT>: [Errno -2] Name or service not known

Environment

VMware Cloud Foundation 9.x
VMware vCenter 8.0
VMware ESXi 8.0
VMware NSX Manager 4.2.3

Cause

The ESXi host is unable to resolve the FQDN of the NSX Manager, which results in an NSX installation failure and an error during the import task.

Resolution

Configure the appropriate DNS settings so that the ESXi hosts can resolve the FQDN of the NSX Manager.

Additional Information

Transport node status becomes INSTALL FAILED due to DNS issues on the ESXi
