[Paraview] WebSocket Connection lost in ParaviewWeb

[Sebastien Jourdain]

The web socket forwarding should be handle by Apache at that point and it
seems to be done by Jetty?
In your jetty configuration, the session URL might not be valid when using
Apache as a front-end.

Moreover, which Apache setup did you used? 2.4+ like for the EC2 Amazon
documentation or the old one with the Python module?
