8080 exposes a rest api got bouncers, csli and communication between crowdsec agent and local api.
Can we change that port? Or will it break all communication between the agents of your systems? I actually need that port for another interface of a webapp and I m not sure I can change it.
You can change this in the the /etc/crowdsec/config.yaml . Please keep in mind, that you will have to modify /etc/crowdsec/local_api_credentials.yaml accordingly.
