Unable to connect to the remote server

We are executing a rest call while using the "Run Script" operator. The inline script of the .ps1 uses the powershell cmdlets: invoke-restmethod or invoke-webrequest

However, when executing the operator it returns the following error:



Invoke-RestMethod: Unable to connect to the remote server

At C:\Temp\.c2otmp\dc200559-aa2c-4795-b49a-5508be322cb7\c2ouscript.ps1:23


+ Invoke-RestMethod -Uri $uri -Credential $cred -Method Get -ContentType ...



Release : 4.3

Component : Process Automation



The problem was solved after adding the URL to the trusted sites. The issue was with trusted zones and worked once the site was added to the trusted site list to execute api calls. This is an operator system / browser setting. Not an ITPAM setting. 

Additional Information

If you are experiencing this type of issue than executing the following powershell statements may help you isolate the cause. It is recommended to execute these statements:

  • Across several machines. With the same version of powershell as the problematic server. If the same operator works on a different machine, compare powershell versions on the two systems. 
  • Through itpam and also manually executing it on the servers


Powershell statements: 

  • Get-ItemProperty -Path "Registry::HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings"

  • [System.Net.WebProxy]::GetDefaultProxy() | select address

  • [System.Net.WebProxy]::GetDefaultProxy()


  • $IESettings = Get-ItemProperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'

  • $Proxy = "http://$(($IESettings.ProxyServer.Split(';') | ? {$_ -match 'ttp='}) -replace '.*=')"

  • $Proxy

  • $(get-item "HKCU:\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMapKey").property

  • $(get-item "HKLM:\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMapKey").property
