Powerscale API Not Returning Invoke-RestMethod

Question

Hey all, got a question if anyone has seen this before. I'm writing some custom powershell to parse some information from our isilons. Last night when I was working on it, everything was returning 100% fine, but when I came in this morning I was unable to parse anything from an Invoke-RestMethod call. Even when taking the commands out of the script and running them individually it fails.

So here's the function I'm calling in powershell:

functionGet-AccessZones {
param (
        [string]$IsilonIP
    )
try {
# Access zone endpoint
$accessZoneEndpoint="https://${IsilonIP}:8080/platform/1/zones"
$zoneResponse=Invoke-RestMethod-Uri $accessZoneEndpoint-Headers $AuthHeader-Method Get -UseBasicParsing
return$zoneResponse.zones.name# Return array of zone names
    }
catch {
Write-Host"Failed to retrieve access zones from $IsilonIP"-ForegroundColor Red
return@()  # Return empty array on failure
    }
}

and then the call in my code:

$accessZones=Get-AccessZones-IsilonIP $CurrentIP
if ($accessZones.Count-eq0) {
Write-Host"No access zones found for $CurrentSite at IP $CurrentIP"-ForegroundColor Red
continue
    }

Even if I hit the URL'https://${IsilonIP}:8080/platform/1/zones' in my browser, it authenticates properly and displays the info properly. But even if I come straight to a shell outside my script and run:

Invoke-RestMethod -Uri https://${IsilonIP}:8080/platform/1/zones -Headers $AuthHeader -Method Get -UseBasicParsing

It returns:

Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send.
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

Just curious if anyone had seen this or had an idea before I opened a support call.

Just for the answer. I thought I had SSL right on my server, but the self signed certs and everything weren't right. Was able to bypass the error by adding

Add-Type @"
using System.Net;
using System.Security.Cryptography.X509Certificates;
public class TrustAllCertsPolicy : ICertificatePolicy {
    public bool CheckValidationResult(
        ServicePoint srvPoint, X509Certificate certificate,
        WebRequest request, int certificateProblem) { return true; }
}
"@
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

To my script, and fix permanently by importing our wildcard SSL cert to the HTTPS site.
