Connect-CIServer: Invalid API version requested

Recently my script stopped working to connect to vCloudDirector. I consume vCloudDirector from a managed service company and sometimes the version changes without me knowing or having a simple way to check it. Just now this happened to me again, usually this then means my PowerCLI script starts failing.

A simple install or update module didn’t work.

Install-Module -Name VMware.PowerCLI
Update-Module -Name VMware.PowerCLI

I was faced with the following errors.

PackageManagement\Install-Package : Authenticode issuer 'CN=DigiCert Trusted Root G4, OU=www.digicert.com, O=DigiCert

After reviewing, I was not concerned that the signing authority changed. Therefore, I went ahead and installed the latest version by skipping the publisher check.

Install-Module -Name VMware.PowerCLI -SkipPublisherCheck -Force

And boom, this let me again connect to the vCloud Director with powercli.
