I have downloaded prebuilt binary and ran on debian 11. Server gives message 404 page not found when I open browser at http://ip:8080

then a crash in server console outputs this:

if you really need password auth you have to install openvpn-user - just make it available throw PATH variables and dont forget about execution rights on the binary or dont use flags --auth

Yes I don't know what is causing the problem. I'm not used with go language and don't know what to try. I'm working right now with docker flavour and having some issues also but I think I'll go with this route and try to make it usable.
