Hello,
I started using a reverse proxy server such as CloudFlare to serve my Ownclould file server to the public. Unfortunately I am getting an error "This operation is forbidden" when viewed publicly and everything works fine when I access the server directly by changing the hosts file. I've added all the Proxy IP address in the config file like this:
trusted_proxies' => array('XXX.XXX.XXX.XXX', 'XXX.XXX.XXX.XX1', 'XXX.XXX.XXX.XX2'),
'forwarded_for_headers' => array('HTTP_X_FORWARDED', 'HTTP_FORWARDED_FOR', 'HTTPS_X_FORWARDED', 'HTTPS_FORWARDED_FOR')
Still getting the same error. Viewing the owncloud log files shows nothing. Also nothing strange in Apache's access or error logs.
Server configuration
Operating system: Centos 7.2
Web server: Apache
Database: SQLLITE
PHP version: 5.4.44
ownCloud version (see ownCloud admin page): 9.1.4 (stable)
Updated from an older ownCloud or fresh install: Update
Special configuration (external storage, external authentication, reverse proxy, server-side-encryption): reverse proxy
ownCloud log (data/owncloud.log)
