caused by GaiException: android_getaddrinfo failed: EAI_NODATA. Googling for this I found this: http://stackoverflow.com/questions/9475024/httpresponse-using-android-issue-execute-always-causes-exception

I will try to add <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> and we will see.

Added android.permission.ACCESS_WIFI_STATE
Marking as fixed in Aedict 3.39.9, please reopen if the problem persists.

The customer's phone is Nexus 5, Android 6.0.1. I have found this bug report, perhaps this is an Android issue after all: https://code.google.com/p/android/issues/detail?id=197641

Adding android.permission.ACCESS_WIFI_STATE did not help, reverting back so that Aedict3 does not ask for unnecessary permissions.

Unfortunately I have no idea what's causing this. Apparently there are no custom security settings for Aedict blocking internet access, perhaps this really is a bug in that particular Android phone? Unfortunately, there is nothing I can do, closing as bug in Android.
