My ipad cant log in MashZone

Hi, 

I have MashZone 2.3, and I want to view my mashapps in the ipad, so when I try to log in into the app, it says:

Server "http://xxxxxxx:16360/mashzone" is unavailable or must be updated

-In SERVER I put also kthe IP, or hostname's LapTop and it doesnt works

-So my Laptop and the ipad are connected in the same wireless network, 

-I create a user only for the ipad

-I dont know if I have to write something in the "TENANT" field...

-I have the lastest Mashzone viewer version from Apple AppStore

Do you know what Im doing wrong, or if Im missing something?

Regards and thank you so much!
