redis not working
I'm getting problems with whatever program redis is.
when running start.sh i get
```
nohup: appending output to 'nohup.out'
nohup: failed to run command 'redis-server': No such file or directory
```
and then nitter fails to connect to redis

What I wanted was for nitter to be run on local port 3900 and then have my nginx thing direct traffic of a domain to this localhost port.

I'm confused to whether I'm supposed to use 
```
docker run -v $(pwd)/nitter.conf:/src/nitter.conf -d -p 3900:8080 zedeus/nitter:latest
```
to start the server or start.sh

All ports in nitter.conf are unchanged

Currently I just get 502 bad gateway when trying to connect
