This file documents my troubleshooting methodology for configuring nginx to reverse proxy https traffic, and reverse proxy non https traffic on tcp/443.

## Context
I have an OpenVPN server set up on a Raspberry Pi (`192.168.0.2`) listening on TCP/443 so that it's able to function on most networks. There are enough clients configured that I do not want to remake the server.

I would like to serve https traffic from a server (`192.168.0.6`)


Right now, it appears that I can't do that with one IP because that would require two separate nginx components listening on the same port, or that's what I ascertained from the logs.

I modified `/etc/nginx/nginx.conf` to include this block underneath the `http` block:
```nginx
stream {
	server {
		listen 443;
		proxy_pass 192.168.0.2:443;
	}
}
```

When trying to start with that change applied, I got the error:
```
nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use)
```
