SqlSentry PowerShell - User Permissions

Im facing some issues using the Powershell execution at SQL Sentry. I Tryed with diffrent options for trying the script in the same server but none of them worked (localhost, 127.0.0.1, <ip of the host>, <dns hostname>  

Down anyone solved this issue?  do you know what are the permissions required for the user used to execute the powershell scripts?
