RESOLU Preview libreoffice

I'm on a share host apache 2.4 php 5.6 mysql 5.5 oc 10.0.3 + calendar + pdf preview and onlyoffice
I copied libreoffice binary on folder www/libreoffice, added 'enable_previews' => true,
in the config.php
I get following message at the time I give the address on "parameter" + "general" on my owncloud page.

{"reqId":"Wik-KgoAPV4AAH6cl@AAAACd","level":3,"time":"2017-12-07T13:16:26+00:00","remoteAddr":"","user":"gilles","app":"PHP","method":"PUT","url":"\/nuage\/owncloud\/index.php\/apps\/onlyoffice\/ajax\/settings","message":"file_get_contents(https:\/\/\/libreoffice\/coauthoring\/CommandService.ashx): failed to open stream: HTTP request failed!

I suppose uploding libreoffice binary is not enough right ?

Correct. Recommend to run CODE from Collabora to test it out.

It's a pity, it does'nt look like being a solution since I'm on a shared host. I've no possibility to make any installation like cloudsuite. The only thing that I can do is updload files.

I saw that collabora online is available on the owncloud's market (top left on owncloud page). Unfortunately, it requires the installation of collabora cloudsuite.

Thak you anyway for the answer.
