AR Management Shell - Remote Server not connecting

Hi, 

I typically write and execute all my PowerShell scripts that need to interact with AR from the AR Server itself and that's been no issues. 

I always use the below and this connects with no issues. 

$QADServer = "SERVERNAME"
 Connect-QADService -Service $QADServer -Proxy

I have a requirement where i need to connect to the AR Service from a remote server to run some PowerShell code. 

Just as a test i knocked up the blow. 

$Password = ConvertTo-SecureString "PasswordHere" -AsPlainText -Force

Connect-QADService `
-Service "SERVERNAME" `
-ConnectionAccount "DOMAIN\Account" `
-ConnectionPassword $Password

This then returns the error below. 

Connect-QADService : Server not exist or could not be contacted: SERVERNAME

It does not matter how i try and connect i keep getting the same message. 

I can open the MMC console with no issues so it does connect with that , no issues at all.. 

Am i missing something?
