Cause

You may have a firewall blocking connectivity from your PowerCLI client and the remote ESXi host in SDDC

Resolution

1) Login to your VMC SDDC and go to Network & Security (Legacy View) or Open the NSX Manager
2) Check the Management Gateway Firewall (MGW)
3) Ensure there is a Firewall rule allowing access from the remote PowerCLI machine to the ESXi hosts on TCP 902

See this document for additional details on Configuring the Management Gateway Firewall Rules
