Hotspot on OmniTek U-5Hnd

Hello
I am using the OmniTek U-5Hnd now. It is my first Mikrotek. I want to activate the Hotspot interface so that the login screen can appear for users.
Unfortunately It does not work. I activated WLAN. And now I have an Access Point (Unifi from Ubiquiti) that is connected to ether2-master-local (ethernet2). WLAN is working perfectly with Unifi perfectly.
I followed this tutorial to activate the Hotspot interface: http://wiki.mikrotik.com/wiki/Hotspot_server_setup

I did reset the configuration and repeated again and again. Has someone activated hotspot interface? Or I am doing a work on wrong devices. Please just give me some feedback if you know some information or hints how to make forwards here?

Thanks

MT hotspot works good enough. Maybe there is some configuration issue. Please post your configuration.
