Jupyterhub: Websocket connection issue

[Jean-Baptiste-Lasselle]

Okay I have this exact problem: https://github.com/jupyter-server/jupyter_server/issues/1310

• I tried setting the options of Jupyterlab as they say like the --GatewayBlablablaa.kernel_ws_connection="" and some other equivalent more recent ones like ZMQChannelsWebsocketConnections.kernel_ws_connection, but it wouldn't work
• ANd I think I found the solution, which may rely in the nginx config (yet im not sure i haven't changed the nginx cnfig for a long while i don't see why ....) : https://stackoverflow.com/questions/42350182/jupyter-notebook-keeps-reconnecting-to-kernel

Well I hope I fix that soon its annoying, and well the Jupyter stack i have here has some unstability, i don't like that at all, but we'll se later.
