OpenVPN Connect Android 4.3

[mrserrao]

Hi all.
We are trying to run OpenVPN Connect in a embedded tablet in our office, for an inside app. But for some reason on LTE with android 4.3 it doesn't connect:

Code: Select all

As you can see on line 24 there is a message:

Code: Select all

3205-10337/net.openvpn.openvpn D/OpenVPNService: SOCKET PROTECT: fd=51 protected status=false

I suspect this is the reason why, because on another android device with Android 5.0 , I can connect successfully, and this line is changed to

Code: Select all

3027-4055/? D/OpenVPNService: SOCKET PROTECT: fd=49 protected status=true

I also tried to connect using the other app ICS-OpenVPN and indeed I managed to connect it, but on the logs there is a message like this:

Code: Select all

Could not protect VPN socket

But we would prefer to use the official app, due to security constraints.

If anybody can help or have some suggestion thanks in advance.
