OpenVPN DDWRT TLS Key Negotiaion Failed

[anthonywkho]

Hi, I have a problem in connecting to a DDWRT flashed router via Openvpn (using a client of windows 10 machine), the client log is as follows and can anyone help? I researched a lot and tried most of the stuff suggested by people but still does not work. So your help is much appreciated.

On the DD WRT (server), I have already changed the private IP subnet to 10.8.0.0 and also I copied the ta.key file content onto the section of TLS Auth (is it correct)? In the client.ovpn, i can see the line tls-auth ta.key 1 do i have to add tls-auth ta.key 0 in the router section as well?

I am quite tired in trying to get openvpn work but it took me too much time but I don't want to give up after spending so much time already.
Thanks
