Websocket gateway problem

I have tried to install Lucee 5 with a websocket gateway (This implementation: https://github.com/quetwo/railoWebSocketServer). In the version 4.5 of Lucee everything work perfectly.

In version 5, impossible to communicate with my channels (Error during WebSocket handshake: Unexpected response code: 404). Nothing in the logs file and everything seem to work normaly in the admin panel.
