Unable to login with curl or provided script

I filled out .env with my login, kept the port the same at 8080, then did the following:

1. Built with `docker build -t "boxing/boxrec-docker" .`

2. Ran using `docker run -p 8080:8080 boxing/boxrec-docker`

Output of 2:

3. Tried using `./scripts/login.sh` and `curl -d "username=XXXX&password=XXXX" 127.0.0.1:8080/login`

I get a curl error: `curl: (56) Recv failure: Connection reset by peer`. When elaborated with a `--ascii-trace`, it says:

```

This happens on master and the 1.1.0 tag. I'm on Arch Linux. Happy to add any extra info as needed
