Realtime WYSIWYG Editor 15.10

When using the debug mode while trying to edit collaboratively in WYSIWYG mode, we get this error message:

"GET /xwiki/websocket/xwiki/netflux HTTP/1.1" 404 41153

Seeking for this error message on the web, I found this lead here on the forum:

However the XWiki and tomcat version used by the-glu were older.
From that thread I found this bug report:
https://jira.xwiki.org/browse/XWIKI-21625?jql=project%20%3D%20XWIKI%20AND%20component%20%3D%20Realtime
« You shouldn’t have to force the page lock to enter a realtime editing session»

  • Affects Version/s: 15.10

So we just need to wait, or is there anything we can do to try improve it?
