Z-Push delivers only empty responses

Hello everyone,

my Z-Push installation with Kopano backend delivers only empty responses. Kopano (inkl. WebApp) works perfectly fine for me.

        include /etc/nginx/snippets/z-push-php.conf;
    }
}

I have no idea how to proceed from here as there is no error or anything giving me any guidance. Hopefully someone has a hint for me.

Hi @faulix,

just to be sure - you are using debian’s repositories for both kopano and z-push, not kopano’s and z-hub’s?

Besides the empty email responses - does the email, calendar, contacts sync work correctly?

What is the LOGLEVEL value in /etc/z-push/z-push.conf.php? For the debug purposes you should set it to LOGLEVEL_WBXML and post the contents of z-push.log after responding an email.

Which PHP version is on the system? Are you using PHP-FPM?

There is a post of me where this is exactly explained on the forum.
All you need todo is translate it to nginx, mine is based on apache.
(sorry, i cant look it up atm).
