Dear Patrick,

The combination of 
  1- SSL certificate (can be disabled)
  2- Python 2 on the client side (this is supposed to be supported, but
     python 3 is preferred)
  3- Client started by the main script (can be started by hand)
might have been only rarely tested.

With the hope to isolate a bit the problem, could you try again with only
some of 1-, 2-, or 3- ?
To disable SSL, try to pass server.ssl=no on the command-line.

Pierrick
