This really shouldn't impact the API at all - at least, you shouldn't see
any 404 errors or anything like that.  I'm not sure about the actual
connection stream, though.

Two things come to mind:
- Some sort of incompatibility in how HAProxy handles WebSocket traffic,
particularly if it is trying to establish it and then dropping it.  I'm not
sure off the top of my head if HAProxy supports, doesn't support, or is
ignorant of the use of WebSocket.
- A parameter is being dropped from one of the API or tunnel calls, like
the token, somewhere along the way - perhaps in HAProxy somewhere.
