Having trouble setting up docker-compose
My full steps were
```
git clone https://github.com/zedeus/nitter
cd nitter
nvim ./docker-compose.yml # set ports to "127.0.0.1:3300:8080" and image to "quay.io/unixfox/nitter:latest" (i'm on arm)
cp ./nitter.example.conf nitter.conf
nvim ./nitter.conf # set hostname to my domain name and set redistHost to nitter-redis
docker-compose up -d
```

`docker logs nitter` then gives me 
```
Starting Nitter at http://nitter.net
Failed to connect to Redis.
```
What did I do wrong?
