Windows – Executing a powershell script through batch file

I am trying to execute a powershell script through a batch file, at the moment I am only testing this to get it running so the .ps1 file is simply a hello world script.

This ALMOST works fine except there is a spanner to throw into the works;

I am trying to have the .ps1 stored in a remote location (on a shared NAS to be specific). This works when I have the .ps1 saved locally and point the .bat to the local .ps1.

However now that the .ps1 is in the remote location I am thrown with the following error;

"file (pathname) cannot be loaded. The file (pathname) is not digitally signed. The script will not execute on the system"

Now I am aware of execution policies and mine are as follows;

MachinePolicy  =   RemoteSigned
UserPolicy     =   Undefined
Process        =   Undefined
CurrentUser    =   RemoteSigned
LocalMachine   =   Bypass

I have tried changing CurrentUser to Bypass but I am thrown with the following;

Windows Powershell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope

Any ideas would be greatly appreciated!

Sorry if this has been a lot of information! If any of it is unclear feel free to ask me to clarify! I'm fairly new to all of this!
