Big-Ip edge client on Android

Hi!

Windows client works fine. I just set VPN address and select client sertificate.

But I can't connect to corporate network on my Android device. I create new connection, set server name and choose client sertificate. I choose my vpn connection in the Connection tab, then press connet button. App shows "Connection to server faild" without any additonal information.

Please help to setup the Android client.
