Ok, client created but still dame Error, openvpn failed to restart.

Now, its possible to download ovpn. After downloader, i have a {username}.ovpn.txt file. ( why txt ?).

This file is not reconized by openvpn client. ( Try on Android for the moment.)

Ok for Android is not supported TAP, only TUN.

But impossible to change this, beacause After édit server.conf, and restart, this file is "restored" by default.

So, i have 2 problems,

1- create user by control panel, with Error "failed to restart openvpn"

2- TUN/TAP mode, impossible to edit and save a New server.conf after restart  

Please help me .
