R8000 OpenVPN certificate issue

After installing OpenVPN 2.4.8 I can no longer connect. When trying to connect I receive the following error in the client log file:

WARNING: No server certificate verification method has been enabled. See http://openvpn.net/howto.html#mitm for more info.

Going to that page didn't actually tell me much besides putting: remote-cert-tls server in my ovpn file. That solved the issue above, but now I see: OpenSSL: error:140AB18E:SSL routines:SSL_CTX_use_certificate:ca md too weak

Every page I've found says upgrade your NightHawk Firmware to the latest and that will fix the signing issue. My current Firmware 1.0.4.46_10.1.63, but no such luck fixing the problem. I did find OpenVPN 2.3.18, which works, though I get a couple of errors along the way. 

Crossing my fingers someone has the answers. 

thanks in advance.
