openvpn server on RT-AC68U not working

[pplui]

I use to have my openvpn server running with no problems in my AC3100
My setup is WAN<>ISP modem<>AC68U<>LAN

I had to change it because the ac3100 was loosing connections

I forwarded UDP 1194 port to my AC68u, exported the OpenVPN configuration file, created two users.

Then, i imported the config file into my android phone, but i have no connection

I tested it with a wrong username/password intentionally, it looks like it never reached my asus router
Here you have my androind openvpn log (changed address to xx)
The DDNS is working as expected
I have no wait to have a log from my ISP modem

Change this default 1194 port to something else. You'll be scanned multiple times a day. Verify your DDNS is pointing to the correct WAN IP address. I would disable IPv6 in both DDNS and VPN Server. If you have just set your VPN Server - reboot your router and try again.

What port you have forwarded on a Modem? Modems are just bridges with no routing. Your ISP device must be a Modem/Router to do that with your AC68U in double NAT behind it. Check what's going on there because your connections description doesn't match your actions.

Done, thanks!
Good advise about port 1194, changed it to something else

Problem was that i entered 11194 instead of 1194
