An empty string also produced the error.
However, I created a bridge using the bridge utilities package
$ sudo apt install bridge-utils
$ sudo brctl addbr bluez
And then used
server.Register('panu', 'bluez')
This enabled the connection to be accepted from the client to happen
without error.

I think the bridge probably needs more refinement as there does not
appear to be a route between the two devices still.
Any pointers on that appreciated.
Thanks again for your help on this Luiz.

Barry
