ERROR: auth_key_id should be NULL

I followed every step to make it work. I'm using Commit 76824c29a6 on Ubuntu 14.04.2 LTS.

After the command

./telegram-cli -k tg-server.pub -c telegram.config

I get

/usr/src/tg/zabbix# ./telegram-cli -k tg-server.pub -c telegram.config change_user_group: can't find the user telegramd to switch to Telegram-cli version 1.2.0, Copyright (C) 2013-2015 Vitaly Valtman Telegram-cli comes with ABSOLUTELY NO WARRANTY; for details type show_license'.

Having telegram.config edited like:

default_profile = "zabbix";

 zabbix = {
    config_directory = "/usr/src/tg/zabbix/";
    test = false;
    #msg_num = true;
    binlog_enabled = true;
    log_level = 2;
};

I'm able to type my cell phone, but then I receive a SMS on it saying:

You are using an outdated app that doesn't support 2-step verification. Please update your app to log in to Telegram.
