I have a SharePoint site in my development environment and on it i have Nintex Workflow and Nintex forms (for Smart Phone).

in App Studio i have created a new app with connection to my sharepoint site as (http://<server ip address>:<port> )
when try the app on my android device it is unable to connect to the sharepoint site on my server and gives this error:

Error: Ensure the server you are trying to connect to is available and try again.

trying the same connection with Nintex Mobile App it is working fine. but from App Studio I am getting the above error.

Can anyone give me input on this issue.

Thank You

Mohamed Salem.
