I can`t use OX Drive/OX Mail on Android Mobile Device (it works fine on IOS)

When ssl is enabled on apache then I`m getting an error on OX Drive:

OX Drive URL https://ox.astroline.pl - server is not supported.

My apache2 configuration is:

Code:
<VirtualHost *:80>
    ServerAlias ox.astroline.pl
    ServerAdmin dbudzowski(at)astroline.pl
    RewriteEngine on
    RewriteRule ^(.*) https://ox.astroline.pl$1
    RequestHeader set X-Forwarded-Proto "https"

</VirtualHost>

<VirtualHost _default_:443>
    DocumentRoot /var/www/html
    ServerAlias ox.astroline.pl
    ServerAdmin dbudzowski@astroline.pl

    RequestHeader set X-Forwarded-Proto "https"

    <Directory /var/www/html>
           Options Indexes FollowSymLinks MultiViews
           AllowOverride None
           Order allow,deny
           allow from all
           RedirectMatch ^/$ /appsuite/
    </Directory>

    <Directory /var/www/html/appsuite>
            Options None +SymLinksIfOwnerMatch
            AllowOverride Indexes FileInfo
    </Directory>

    SSLCertificateKeyFile /etc/ssl/private/astroline.key

Could anybody help me with configuration?
