traefik-bouncer not connecting

[lewisd19]

I am having a strange issue getting the traefik-bouncer up and running. Ive followed the steps and have got it going successfully on two other hosts but for whatever reason the host im attempting to get it going on will not connect to my traefik container. Im not sure what Im missing and super confused.

cscli bouncers list:

also was getting this error which prompted me to nuke the setup and start over:

{"level":"warn","error":"invalid character 'p' after top-level value","time":"2022-11-24T01:29:00Z","message":"An error occurred while checking IP """}

Any ideas? Thanks in advance.

Hello,

I have the same issue.

Here is my setup:

  crowdsec:

    container_name: crowdsec
    ports:
      - "8080:8080"

      GID: "${GID-1001}"
    volumes:

      CROWDSEC_BOUNCER_API_KEY : $CROWDSEC_BOUNCER_TRAEFIK_API_KEY

Have you resolve it ?

Check out the traefik plugin to do the same. Maintainer updates it frequently, with many more config options.

Thanks for the input about the alternate bouncer, but that doesn't help this bouncer. I'm also having issues getting it to connect. If anyone has a solution other than another bouncer.

Which port are you using to connect to crowdsec container?
I figured that crowdsec container for unraid opens two ports: 6060 and 8081
While trying to connect to 6060, I experienced the same issue.
Meanwhile I switched to using traefik plugin and never tried connecting bouncer to port 8081. You can try to point bouncer to port 8081 for crowdsec container, maybe that would solve the issue.

@lewisd19 & @jphp3405
Which host system do you use?

Still having the same issue here (with a stand-alone container as well as when using the plugin). I'm using ubuntu server 22.04.4 LTS as a VM on Promxox.
I don't think this matters here but I do have a ufw aktiv blocking most incoming connections but since this is all routed through the internal docker network the firewall should be irrelevant, right?

Edit: I conducted following tests:
ping traefik-bouncer:8080 from within the traefik container -> works just fine
ping http://traefik-bouncer:8080/api/v1/ping -> results in ping: bad address 'http://traefik-bouncer:8080/api/v1/ping'
