I tried to create a android apk from Pega PRPC 7.2 for our application. Created a certificate set for our Pega application and the build was successfully loaded till 100% and while downloading the build it got stucked and it shows loading button for the last few days ( Please refer attached screen shot for the same) even after restarting the server and clearing the cache this isn't allowing to try to take the new build. 

Any ideas or suggestion to overcome this problem will be appreciable. Thank you
