I'm struggling with my first Carbonio setup since I can't get it work in my network environment.
Carbonio is installed on a Host on a local Network, with a local domain - let's say carbonio.internal - with a private IP address (RFC1918).
For external access I have a nginx reverse proxy on a host with a public IP address. I want to proxy traffic from a public domain - let's say carbonio.example.com - to my internal carbonio host.
Fiddling with my ngnix proxy settings brought me to the point, that the login screen for admin panel loads. But I'm not able to sign in (supposedly) because of an "CSRF referer [sic!] check failed" error.
I guess I need to tell carbonio, that the public domain (carbonio.example.com) is a valid domain and it should stop redirecting URLs, links and requests to the internal domain (carbonio.internal).
Do you know how I can set such a configuration up (without being able to access the admin panel for configuration!)?
