Unable to sync with android server over its own hotspot

[bjester]

Observed behavior

• Two devices on the same external network can sync and communicate
• Two devices connected on one of the device's hotspot cannot sync, but requests do succeed from the foreground process

Errors and logs

Requests like at the beginning of a sync timeout. Sync tasks will appear to stop at:

Run user program, change dir and execute entrypoint

Expected behavior

Unless this is a Android hotspot specific restraint, no difference in this behavior would be ideal.

User-facing consequences

The caveat isn't helpful in offline scenarios, because a third hotspot or wifi AP device is required to facilitate syncing

Steps to reproduce

1. Install Device A with Kolibri for Android
2. Set up a full facility on Device A
3. Turn on Device A's hotspot
4. Install Device B with Kolibri for Android
5. Forget any currently available Wifi APs on Device B
6. Connect Device B to Device A's hotspot
7. Attempt to join Device A's facility from the setup wizard on Device B
8. Observe the device is discovered
9. Observe the import task stalls at 0%

Context

Kolibri for Android 0.16.1
