Error 404 on html5/html5lib/v2.46.rc6/mwEmbedLoader.php

Hi, thank you for your help

First the studio version :

$ dpkg -s kaltura-html5-studio
Package: kaltura-html5-studio
Status: install ok installed
...
Version: 2.0.6-1

The html5 version

$ dpkg -s kaltura-html5lib
Package: kaltura-html5lib
Status: install ok installed
...
Version: 2.46-1

Then the studio.ini

$ more /opt/kaltura/apps/studio/v2.0.6/studio.ini
[general]
component.name = HTML5Studio
component.version = v2.0.6.rc1

[defaultKdp]
widgets.studio.version = v2.0.6.rc1
widgets.studio.name = Video Studio V2
widgets.studio.usage = html5studio
widgets.studio.config = '{"version":"v2.0.6.rc1", "name":"Video Studio V2", "tags":"studio_v2", "ht
ml5_version":"v2.46.rc6", "html5lib":"http://kgit.html5video.org/tags/v2.46.rc6/mwEmbedLoader.php"}
'

Finally in local.ini

kmc_version = v5.40.3
studio_version = v2.0.6
html5_version = v2.46
kmc_login_version = v1.2.8
