There might be a setting in BubbleUPnP that you can change to solve this. I suggest you ask about this on the BubbleUPnP forum thread if you haven't already done so.

I stumbled across a very old post of yours on the OpenHome forum.

It refers to

The UPnP Device Architecture specification defines the following error codes on page 53:

501 Action Failed May be returned in current state of service prevents invoking that action.
