Openvpn cannot find host for dns

[Bboy486]

I'm trying to connect to my home PC.

I turned on the VPN in my r6700 router, I downloaded the files for both my Windows 10 PC as well as my Galaxy S8 plus Android device, I added the proper file to openvpn, however when I try to connect it tells me that my Dynamic DNS which is no IP cannot resolve to host.

I don't know what's the issue my Dynamic DNS works and everything else I use including Blue Iris IP cam and others.
