Can't create new location in Indoor App

To be able to start using indoor location feature, it is a must to create location using Indoor app on iOS. However, after walk around to location the map, I can’t save with return error message “The server cannot or will not process the request due to an apparent client error”

Furthermore, I also face an error when tried to sync with beacon with Estimote application. During syncing the application always crash without any error message (suddenly close). Could anybody help on fixing this issue?
