"The remote server returned an error: (407) Proxy Authentication" - This is another issue I faced when working with VMware PowerCLI, Although I had already resolved another error in VMware PowerCLI Connect-VIserver Could not connect using the requested protocol, Only the difference was it was not connection error but throwing error when running PowerCLI cmdlets. Example Get-VM or Get-VMHost, Since I was received different error with different cmdlet (operation) so I thought documenting it as a troubleshooting guide for my Team Members.
Get-VM

To start troubleshoot, I checked the current configuration of PowerCLI, it indicated Session Scope is using UseSystemProxy as ProxyPolicy.
C:\PS>Get-PowerCLIConfiguration Scope ProxyPolicy DefaultVIServerMode InvalidCertificateAction DisplayDeprecationWarnings WebOperationTimeout Seconds ----- ----------- ------------------- ------------------------ -------------------------- ------------------- Session UseSystemProxy Multiple Ignore True 300 User Multiple AllUsers Ignore
Changed the Session scope to use NoProxy with below one-liner command. I had used same steps to resolve other issue VMware PowerCLI Connect-VIserver Could not connect using the requested protocol.
C:\PS>Set-PowerCLIConfiguration -ProxyPolicy NoProxy -Scope Session Perform operation? Performing operation 'Update vSphere PowerCLI configuration.'? [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): y Scope ProxyPolicy DefaultVIServerMode InvalidCertificateAction DisplayDeprecationWarnings WebOperationTimeout Seconds ----- ----------- ------------------- ------------------------ -------------------------- ------------------- Session NoProxy Multiple Ignore True 300 User Multiple AllUsers Ignore
Once the ProxyPolicy is configured, I ran few PowerCLI commands to verify and it is was successful.
