Interestingly I downgraded to server version 4.3.23 it works again, but let me tell the full story.
I ‘ve a Debian Wheezy 7.x (x64) Server running NX Server.
From within the LAN (through a NAT-Router within the LAN or directly connected) I am able to connect to the Server from Windows, MAC and Android with recent client versions to NX Server version 4.3.23 (64Bit) and version 4.3.30(64Bit)
From my Home network (NAT Router, 50MBit connection, no firewall at home, no firewall at Serverside) I am able to connect to NX Server ver. 4.3.23(64Bit) from Windows, MAC and Android recent clients
With 4.3.30(64) I can can connect from home with Windows and MAC but not from Android.
From Android (v 4.2.25) it is not possible to create a working connection to NX server ver. 4.3.30. (Confirmed on several Android devices).
The connection itself works, I can see the initial remotescreen but then the client hangs, does not react to any touch gesture nor let me exit the client. While waiting for connection, which can take up to 5 minutes, sometimes it is not even possible to the Back-Key. Sometime I get a ForceClose.
Where can I find client logfiles on Android or enable debug logs on Android (beside the very limited logcat output)?
Now that I’ve a point to look further what exactly is going on I can make some tests in the next few days and provide client and server logs.
NX 4 is exactly what I`ve looked for for many years – and know/watch for at least that 10 years . A mixture of cross platform VNC,RDP,Chrome Desktop. A product I really want to help to make it better and better.
best,
