Since the default port `8080` is used by other service I have changed it to `7373` editing these files

```auto
config.yaml
local_api_credentials.yaml
crowdsec-firewall-bouncer.yaml

```

and replaced all `8080` port entries with `7373`.

Doing this the crowdsec service starts without crash and apparently seems running correctly but unfortunately when I launch  
`cscli metrics -u http://localhost:7373`  
I get the error

> failed to fetch prometheus metrics : GET request for URL “[http://localhost:7373/metrics](http://localhost:7373/metrics)” returned HTTP status 404 Not Found

and if I try to open `localhost:7373` in browser I get a 404 error too, without any page to confirm crowdsed is up and running, but service status results active with a crowdsec service listening on port `7373` and another listening on port `6060` as specified in config

I use Debian Bullseye on ARM 64bit.

Note: before installing it I had already a Prometheus service running on port `9090`, but If i had understood correctly the prometheus port `6060` in CrowdSec config refers to the CrowdSec service where it supposed to fetch data.

Hello,

Prometheus listen by defaults on port 6060. You can change it in your config.yaml :

```nohighlight
prometheus:
  enabled: true
  level: full
  listen_addr: 127.0.0.1
  listen_port: 6060

```
