host name can't be null using Grails Spring Websocket Plugin

i'm developing a simple web application using the spring websocket plugin for grails.

While in local everything works well, deploying the application on a testing server online, i receive those execptions:

Chrome console:

Error during WebSocket handshake: Unexpected response code: 500

Tomcat Console:

I'm using Tomcat 7.55, Ubuntu Server

Solution

  • Solved! I've to add a mapping in the hosts file, mapping the host name with the private IP of the machine in the data center.
