Cause

This issue occurs due to the proxy settings in the environment.

Resolution

To resolve this, check the proxy settings using the PowerCLI and set the proxy to No Proxy.

To set the proxy setting to No Proxy:

1. Run this command to find the current proxy settings:
   
   Get-PowerCLIConfiguration
   
   You see an output similar to:
   
   C:\PS>Get-PowerCLIConfiguration
   
   Proxy Policy Default Server
   Mode
   ------------------------- ---------------
   UseSystemProxy Single
   
   Note: This output indicates that the PowerCLI is using the System Proxy.
   
   
2. To change this setting, run this command:
   
   Set-PowerCLIConfiguration -ProxyPolicy NoProxy -Confirm
   
   You see an output similar to:
   
   C:\PS>Set-PowerCLIConfiguration -ProxyPolicy NoProxy -Confirm
