  • During Edge node deployment, NSX-T Manager will connect to the ESXi host for transferring the required files.
  • This issue occurs when NSX-T manager is unable to communicate with ESXi host on TCP port 443 for transferring the edge vmdk files.


NSX-T requires TCP port 443 to be open between NSX-T manager and ESXi hosts for management and provisioning connections.
  • To resolve this issue, disable any firewall rules which may be blocking traffic between NSX-T Manager and ESXi hosts over TCP port 443 and retry the edge deployment.
  • To test connectivity between NSX-T Manager and ESXi hosts, use the below command from NSX-T manager root login
nc -zv <nsxt-manager-ip> <tcp port no>

Output of a successful connection:

root@324:~# nc -zv 443
Connection to 443 port [tcp/https] succeeded!

  • If port 443 needs to remain blocked, deploy the edge from the vCenter using an edge ova and manually register it with the NSX-T Manager. For more information refer NSX T Documentation .
