ox6-mobile-v2

Dear OX community,

In our setup we make use of the ox6-mobile-v2 modules. (for testing etc..) In our setup de OX server is separated from the internet via a Apache2-reverse-proxy (rp.) The apache2 config of this reverse proxy looks like:

<VirtualHost *:80>
ServerName webmail.example.com
ServerAlias webmail
RewriteEngine on
RewriteLogLevel 0
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^/(.*) https://%{SERVER_NAME} [L,R]

This work perfectly for the normal OX traffic (e.g. login via the webinterface, read/write email etc..) but the mobile interface keeps complaining with:

"An error occured

Error Code: Can't connect to backend. Please check server settings in ox-access.conf"

The ox-access.conf looks like:

# change this file and run the command
# /opt/open-xchange/sbin/update-cache.manifest

https://172.19.100.65/ajax/

# http://myox.example.com/ajax/
# *
# for google maps the app needs access to this address

http://maps.google.com

(Yes I did issue the command: /opt/open-xchange/sbin/update-cache.manifest /var/www/ox6-mobile-v2/cache.manifest /var/www/ox6-mobile-v2/cache.manifest.in /var/www/ox6-mobile-v2/ox-access.conf)

Some logging while trying to open the ox6-mobile-v2 site (this logging is NOT the reverse proxy but from the OX-machine!)

Strange!

Any ideas are more than welcome!

Kind regards,

Hi,

the error is caused by a status code 0 and an empty response to an ajax call. If you could provide me a log from Firebug I can say something more specific.

Regards,
Alexander
