Teamviewer Android Host OFFLINE but is connected to the internet

Intertouch

hi,

I installed teamviewer host on an android 6.0, I state that it is not the first installation of tw host on an android 6.0 but it is the first time that makes us a strange error.

In a nutshell teamviewer goes offline after some time despite the connection in the android device is fully functional

The special thing is that on 5 identical devices located in the same place with the same internet line, only 3 went offline at different times.

Version Host --> 15.31.117

The only way to review it is to reboot the device.

How can I solve this problem?

Thank You
