So that was the dumbest thing. I have a love-hate relationship with OpenVPN. When it works, it works WELL. When it doesn't, it's usually because of some obscure incompatibility with network devices or a cryptographic oversight on my part, since I've been configuring it and setting it up for the better part of seven years. Anyways, that's just me bitching - I figured I'd put the relevant information here in case some other poor, lost soul has this issue.

I was getting the following error message on OpenVPN 2.4.9 on Windows x64 (Server 2019 Essentials):

This is a markdown file detailing the errors I'm encountering installing Ruby 2.7.5 for my (extremely simple!) Rails 6.0.4.4 application on a fully-updated instance of CentOS 7.

This is the output from the shell:
