OpenVPN Support Forum

Dear community,

I am trying to connect my android with my vpnserver, but the openvpn client cannot resolve host address. This only happens with my phone. I used the same configuration with my laptop and it works perfecly fine. I think I am missing something. I am using the app "openvpn for android" with sslsocks

This is the configuration of my vpn server.
port 1194
proto tcp
dev tun
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
ca /etc/openvpn/easy-rsa/pki/ca.crt
cert /etc/openvpn/easy-rsa/pki/issued/vpn-server.crt
key /etc/openvpn/easy-rsa/pki/private/vpn-server.key
dh /etc/openvpn/easy-rsa/pki/dh.pem
server 10.8.0.0 255.255.255.0

auth SHA256

This the client

client
dev tun

remote localhost 1337

<cert>

and this is the configuration of stunnel (sslsocks)

foreground = yes
client = yes
pid = /data/user.../pid
accept = 127.0.0.1:1337
connect = xxxx.org:443
cert = stunnel.pem

There is not enough info here.
could be correct as stunnel is used to vpn through.

Moved back to off topic.
