This is not working for me.
I've tried accessing a local vehicle (regular URL e.g.: 192.168.0.99) and it didn't connect.
It works fine on master.

Console shows:

WebSocket connection to 'ws://192.168.0.99/ws/mavlink' failed:

It only works if I explicitly set the m2r address as ws://192.168.0.99:6040/ws/mavlink.

Working like a charm.
