Problem to connect with kayako chatgateway

[darudev87]

Hi,

I have android 5.0 and i want use your app with my kayako service.

According this guide https://kayako.atlassian.net/wiki/display/DOCS/Kayako+Chat+Gateway i have created all of these to setup correctly chatsecure android app, so i performe these steps:

1. Existing Account Jabber / XMPP Server
2. Insert my user@domain and password ( these data are correct )
3. I go into Advanced Account Settings to insert other parameters as: Server Port: 5222 and Connect Server: chatgateway.kayako.com

Trying to add account, nothing's gone on, account remains in "signing in" mode without error or others

These mine configurations works fine with other apps as Xabber.

Can you give me some suggestions please? Thank you.
