Unable to resolve host "cloud.estimote.com"

Prerequisites

• Put an X between the brackets on this line if you have done all of the following:
  • My beacons have Estimote Location packet enabled (Check it in the Estimote Cloud, or via app)
  • My Android device/devices supports BLE and has Android OS version >= 5.0.0
  • My Android device/devices have bluetooth enabled
  • My app has Location Permissions granted

Basic information

Estimote SDK version: com.estimote:indoorsdk:2.5.4

Android devices affected: Huawei P9

Android OS version affected: Android 7.0

Beacon hardware version: F3.3

Description

If internet connection is available, indoorskd starts location update with no problem. When internet connection is not available, after some time application crashes during call of startPositioning() on ScanningIndoorLocationManager (In my case I need to restart the application 3-4x and then it will result into this error).

Steps to reproduce:

1. Disable internet connection on Android device
2. Attempt to start application and call startPositioning()
3. Watch the result

Expected behavior: Even there is no internet connection, it would be great if call on startPositioning()
would not crash the whole app...

Actual behavior: Currently, when there is no internet connection, calling startPositioning() will result in an exception and in application crash.

(Optional) Additional information

Will this be fixed in new release (3.0.0) ?
I saw some beta versions on maven repository.
Looking forward to full release.
