The Android App “FolderSync” stopped working when I upgraded my ownCloud to Version 7. FolderSync always showed “Bad Request” when testing the connection. ANd when I looked into the Apache log, the requests were closed with “400 Bad Request”. But I found the solution here (german page):
To get FolderSync working with ownCloud 7 you have to add a second line with the HTTPS port 443
to your config.php:
In ${OWNCLOUD_DIR}/config/config.php
:
'trusted_domains' => array ( 0 => 'www.example.org', 1 => 'www.example.org:443', ),
