IBM Worklight - IOS “Downloading Application update” dialog stuck while app is updating

I am having 2 applications which I wanted to run on different ports, I have created two different instances of Liberty core (for e.g SimpleServer & SimpleServer2) doing that I was able to deploy 2 different applications on different port. The application on SimpleServer is working and updating fine But in case of the application on SimpleServer2 I am having the following problem.

I have created and deployed an worklight iPad application on WL server. whenever we update .wlapp on the server it asks for update on iPad and we can download the updates.
But in my case the dialog appears for downloading and never goes off, I can see progress bar fully completed, but it is stuck on downloading.

What could be the possible reasons for this behavior?

We are deploying the application in a production environment, and The worklight versions and build no's are:

WL Server version: 6.1.0.00.20131126-0630

Server build number: 20131126-0630

Development platform version: 6.1.0.01.20140718-1711

Development platform build number: 20140718-1711
