Some hints to test the app:
* To import a openvpn configuration file, copy the ovpn file on the device memory and put in the same folder any external certificates/keys files. Then start the app, tap on "+" button in bottom right corner and choose "Import VPN profile". After the import, the files can be deleted.
* If something goes wrong, check the log. You can see the log by tapping on the vpn name, and so on the LOG tab.
* If the log has errors like "ERROR: Cannot open TUN/TAP" or "Tun device open exception: java.lang.NullPointerException", please try to reboot the device.
* If you have the access on the server side, check the log also on this side.
* Maybe your configuration is not compatible with the last version of openvpn, so try to set the option "Use old stable OpenVPN 2.3.2" in the "Options" section.
* If you cannot resolve the troubles, please send me a e-mail to android@colucci-web.it, I will contact you at soon as possible and I will help you to solve the problem.
