Crashlytics Fabric: не удалось выполнить задачу

У меня возникла проблема, и я не знаю, как ее исправить.

В моем проекте используется crashlytics, но он всегда вылетает и не отправляет отчет. У меня есть исключение TimeoutException:

08-25 03:04:31.876    2856-2856/connectivit.app E/Fabric﹕ Failed to execute task.
