Live trace app returns 204 No Content

I tried installing the new Live Trace app on a test site running in Enonic Cloud, but I get 204 for all service calls (pingws, tasks, dashboard).

On the HTTP-tab, I get an error message telling me that “This might be caused by a front-end server not properly configured”. I do not know how to “properly” configure Apache in this case, as the available documentation is quite limited.

Can you please help me get this working?

The Live Trace app uses websocket connections to the server (XP).
Probably the Apache is not configured to handle websocket connections. They are treated as plain HTTP requests, and closing the connection after the initial response is sent from the server.

Please open a support ticket if this is in Enonic Cloud.
