TLS Error: TLS handshake failed

Hi AnhTVc,

Sorry for bothering you,

I have finished building the openvpn-skrver (your full source code) with Xcode 9.4.1 for iOS10.3. However, when I tested on my iPhone (iPhone 6s), it failed with the following error:

Fri Jul 20 09:24:19 2018 OpenVPN 2.3_git arm-apple-darwin [SSL (OpenSSL)] [MH] [IPv6] built on Jun 16 2017

About vpn server (192.168.0.118), I configured to make it support UDP via port 1194. Both vpnserver and the iPhone can ping together successfully. Could you teach me how to test it?

Thanks,

I think the problem involves configuration. Have you tried this configuration on another app (eg OpenVPN Connect)

Thanks for your suggestion,

I tried this configuration (.ovpn file) with openvpn app which I got from App Store and it worked well. About the openvpn-server, I had to split the configuration file to tcp.ovpn, cert.file and ca.file I'll only try openvpn on ubuntu to verify my configuration.

Again, Thank you very much for the help,
