Problems with Powershell Invoke-WebRequest

[simonapa]

Hello! We have a large number of Powershell scripts supporting our environment, I am working on a new functionality that integrates a more to ServiceNow but have hit a wall.

One script has a number of requirements that will require interaction with SN.

1. Updating/writing to an existing ticket.

2. Searching for a ticket.

3. Reading from a ticket.

From the server that executes the scripts, I am getting errors:

Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send.

At line:23 char:13

+ $response = Invoke-WebRequest -Headers $headers -Method $method -Uri $uri -proxy ...

# Eg. User name="admin", Password="admin" for this code sample.

$user = "admin"

$pass = "admin"

# added the following line to add path to proxy

$proxy = 'http://proxy.url:8080'

$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user, $pass)))

# this was added to assist with SSL Trust message

[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"

$headers.Add('Authorization',('Basic {0}' -f $base64AuthInfo))

$headers.Add('Accept','application/json')

$uri = https://instance.service-now.com/api/now/table/incident?sysparm_limit=1

$method = "get"

$response = Invoke-WebRequest -Headers $headers -Method $method -Uri $uri -proxy $proxy -ProxyUseDefaultCredentials

</code>

Where have I gone wrong? Any assistance would be appreciated.
