OpenVPN and Pi-Hole. Android clients unable to reach the network

[thepasto]

Hi!
I succefully installed and configured pi-hole and i am able to use it in my local network.
Now i'd like to use it with my mobile devices when i'm away. So i tried to install openvpn. Unluckly i'm not able to use it with my android clients.
My opnvpn server is in the same machine where is running pi-hole, its address in my local network is 192.168.1.110

server.conf

port 1194
proto tcp
dev tun
ca /etc/openvpn/server/ca.crt
cert /etc/openvpn/server/homeserver.crt

Here's the result when i try to connect with my mobile device. The client was connecting as well with the server, but internet is unreachable.

In the server log i found some error like this

Sun Jun 18 14:11:44 2017 us=888154 client1/X.X.X.X:59350 MULTI: bad source address from client [X.X.X.X], packet dropped

Anybody can help me to find what my problem is?
If you need more just ask!

Thanks!

Hello,

In your server.conf file, try to modify the line: push "dhcp-option DNS 192.168.1.110" to: push "dhcp-option DNS 10.8.0.1" (your Raspberry Pi-hole IP)

Good luck!
