RV160W-VPN OpenVPN client 'Server TLS version too low'

[CoreyW]

I have an RV160W-VPN.  I recently neede3d to renew expired CA and Server certs for OpenVPN to continue working.  Now when I attempt to login with the OpenVPN client is says 'Server TLS version too low'.  OpenVPN was working fine before I had to renew the certs.

I have the latest route firmware and OpenVPN client (as of time of writing).

Urgently, any timely help would be greatly appreciated.

Sounds like someone that created/signed your certificate/key made a mistake.

The weird thing is that there is nothing in the cert creation that has anything to do with TLS.  And as a second symptom, I get protocol errors with every other VPN type: PPTP, IPSec...

I found that I had to load a even older version of the OpenVPN client in order to get the tunnel to work. - one that permitted TLS 1.0.

So maybe there something environmentally wrong with the router that it can't do anything but TLS1.0?
