Follow up....I think I found what I was looking for in the following:
https://shebangthedolphins.net/vpn_openvpn_windows_server.html
Not owning the url name:)
So approach was (to start), rather than debugging.....I had windows 10 firewall off on server & I thought my router/firewall port forwarding was right (was working on older openvpn configs), and assumed there was something wrong with my configs or way I was generating keys using Easy-Rsa 3. Assumption was if I could start with a "known good" and get that working, then tweak from there (rather than trouble shoot something I had no idea if it would ever work). I.e., many of the how tos I tried didn't seem to work (may have been user error), and it was hard to tell if they ever would. In any event, I liked this site's content because it was clear, and boiled things down to "very simple", and for me on windows 10 (both client and server) works. From here, I can tweak my settings out further to add passwords, additional elements to setting up firewall, keys and configs.
