On my VPS? That would be version 2.4.4.
Well after learning how to telnet in to my router, I found the referenced 'config.ovpn'. No matter how many times I delete tls-version-min 1.2 it comes back. Is it being regenerated when I attempt to connect the VPN? I do not suspect my router as the issue as I just set up ProtonVPN and had no issues enabling it on my router.
