The server code is definitely easier than client code, just a few lines of C, nothing fancy. Did you accidentally close the file or delete something?
It may sound irresponsible but can you try rebooting/reinstalling or even change another Linux machine? :)

I have reset it a few times, same issue. It could be that I have a few users at ones hitting it. I see that on error it terminates the program. Is there a way to get it to just ignore the error without termination?
Oh this simple-vpn-demo doesn't support multiple clients connect to it. You need to extend it in order to do so.

What’s it made to work with? IE can I modify it a bit to work with say.. socks 5? And how? Sorry for all the questions I’m sure you’re busy!
Tunneling and socks work on different OSI layers, but there are projects like tun2socks but I don't have much knowledge about it. I wrote a blog last year explaining this repository a little bit, hope it can be helpful for you to understand how it works: https://post.lxd.me/a-simple-vpn-tunnel-with-tun-device-demo-and-some-basic-concepts

Oh right, I’m more looking for a vpn that I can change the port of, kind of like open vpn but with my own app. Any suggestions. I might try modifying the code of this one to see if I can just get it to ignore the error and keep going
