Sugested change Modify Connect-Rubrik.ps1 to make it Windows Powershell 5.1 compatible:

Replace

            # retrieve bearer token from service account endpoint
            $RestSplat = @{
                Method = 'Post'
                ContentType = "application/json"
                URI = "[https://$Server/api/v1/service_account/session](https://%24server/api/v1/service_account/session)"
                SkipCertificateCheck = $true
                Body = @{
                    serviceAccountId = "$($Id)"
                    secret = "$($Secret)"
                } | ConvertTo-Json
            }

I can confirm this issue in my environment. No errors when executing in Powershell v7.2.8 but receive the same errors using Powershell v5.1.19041.2364

Experiencing the same issue with Windows Powershell 5.1. I think another approach is to make the SkipCertificateCheck a switch parameter to opt into rather than it being hard coded. In my environment all the clusters have CA signed certs so I don't want to necessarily ignore the certificate checks when using PS Core either.
