Getting crazy with Onlyoffice+NC17+reverse proxy

#1

Hi

I’m not able to integrate my OnlyOffice Document Server, when I try to configure the App it shows a error, this is the log:

“method”:“PUT”,“url”:"/index.php/apps/onlyoffice/ajax/settings/address",“message”:“GetConvertedUri on check error: Se ha producido un error en el servicio de documentos: Error while downloading the document file to be converted.”

The problem is only inside my Lan, if I configure a NC instance outside my lan using my DocServer all works ok, but if I try to run in my local NC instance allways fail.

This is my scenary:

Proxy server: internal IP 192.168.100.3, listen to https://mynextcloud.com redirected to http://192.168.100.130 and https://myoffice.com redirected to http://192.168.100.191, both works ok.

Nextcloud server : internal IP 192.168.100.130

Document Server: internal IP 192.168.100.191

Apache (proxy server) configuration:

<VirtualHost *:443>
        ServerName mynextcloud.com
        <IfModule mod_headers.c>
                Header always set Strict-Transport-Security "max-age=15768000; includeSubDomains; preload"

        ProxyPassReverse / "http://192.168.100.191/"
</Virtualhost>

Nextcloud configuration:

'trusted_domains' => 
  array (
    0 => 'mynextcloud.com',
    1 => '192.168.100.130',
  ),
  'overwrite.cli.url' => 'https://mynextcloud.com',
  'overwritehost' =>'mynextcloud.com',
  'overwriteprotocol' => 'https',
  'trusted_proxies' => 
  array (
    0 => '192.168.100.3',
  ),
  'forwarded_for_headers' => 
  array (
    0 => 'HTTP_X_FORWARDED_FOR',
  ),

Any hint?

You should use always the connection over DNS if this works… :wink:
