[Paraview] WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 404

[Sebastien Jourdain]

localhost should work for the launcher unless you have several network
interface.

Moreover, you can use the launcher to issue ssh command to start paraview
on other machines, in which case the host, is not the paraview one.

Would it make more sense if ${launcher_hostname_or_ip_or_localhost}?
