New-PSSession to localhost fails - powershell

Question

I have a script that opens a remote session to the localhost.
I need this to install NuGet on some devices from within a logonscript.
$Username = "Admin"
$Password = ConvertTo-SecureString ‘adminPW’ -AsPlainText -Force
$adminCredential = New-Object System.Management.Automation.PSCredential $Username, $Password
$Session = New-PSSession -Credential $adminCredential
Invoke-Command -Session $Session -ScriptBlock {Install-PackageProvider -Name NuGet -Verbose -MinimumVersion 2.8.5.201 -Force}
Every time I try to run this I get the following error:
New-PSSession : [localhost] Connecting to remote server localhost failed with the following error message : The client cannot connect to the destination
specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the
WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the
destination to analyze and configure the WinRM service: "winrm quickconfig". For more information, see the about_Remote_Troubleshooting Help topic.

Running winrm quickconfig does not change anything...
Following is the output of winrm get winrm/config

Answer 1

Check if the winrm service is running on your localhost:
PS C:\> Get-Service winrm | ft -AutoSize
Status Name DisplayName
------ ---- -----------
Running winrm Windows Remote Management (WS-Management)
Otherwise PS remoting won't work, though you've configured via winrm and have enabled PS remoting via Enable-PSRemoting.

Answer 2

Issue was someone had tampered with the firewall... Thanx for the help guys!
Basically the firewall GPO was blocking remote management

Answer 3

Following worked in my case:
# NOTE: Following is set by Enable-PSRemoting, it prevents UAC and
# allows remote access to members of the Administrators group on the computer.
Set-ItemProperty -Name LocalAccountTokenFilterPolicy -Value 1 `
-Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
