Bubble uPnP Transport Is Locked (Code 705)

I have my music on my laptop (Win 10) and Serviio server installed. I can play all on Onkyo TX-NR609 fine.
I have installed Bubble uPnP on Samsung S3 phone to listen on my phone. I can access all music but it gives code 705 and will not play.
What do I need to make it work?
Thanks
