After restarting the server, everything on it stopped working

Hello all.
I hope someone can help me understand the cause of the problem.
I have TrueNas scale, traefik and crowdsec containers are installed in Docker. I configured the plugin(crowdsec-bouncer-traefik-plugin) 3 days ago. The dynamic configuration contains the following settings

    crowdsec:
      plugin:
        bouncer:
          enabled: true
          logLevel: INFO
          updateIntervalSeconds: 15
          updateMaxFailure: 0
          defaultDecisionSeconds: 15
          httpTimeoutSeconds: 10
          crowdsecMode: stream
          crowdsecAppsecEnabled: true
          crowdsecAppsecHost: crowdsec:7422
          crowdsecAppsecFailureBlock: true
          crowdsecAppsecUnreachableBlock: true
          crowdsecLapiKey: *********** # 
          crowdsecLapiHost: crowdsec:8080
          crowdsecLapiScheme: http
          forwardedHeadersTrustedIPs:
            - 10.0.0.0/8
            - 172.16.0.0/12
            - 192.168.1.0/24                                                        
          clientTrustedIPs:
            - 10.0.0.0/8
            - 172.16.0.0/12
            - 192.168.1.0/24

But yesterday I had to reboot the server, and after that everything stopped working, containers, virtual machine with local DNS. I think the problem is with Crowdsec, because I thought it banned all my local IP addresses and container IP addresses. When trying to run the command “metrics” I see this

admin@truenas[~]$ docker exec crowdsec cscli metrics
level=warning msg="while fetching metrics: executing GET request for URL \"http://0.0.0.0:6060/metrics\" failed: Get \"http://0.0.0.0:6060/metrics\": dial tcp 0.0.0.0:6060: connect: connection refused"

And the same

admin@truenas[~]$ docker exec crowdsec cscli alerts list
level=error msg="error while performing request: dial tcp 0.0.0.0:8080: connect: connection refused; 4 retries left"
level=info msg="retrying in 23 seconds (attempt 2 of 5)"
level=error msg="error while performing request: dial tcp 0.0.0.0:8080: connect: connection refused; 3 retries left"
level=info msg="retrying in 34 seconds (attempt 3 of 5)"
level=error msg="error while performing request: dial tcp 0.0.0.0:8080: connect: connection refused; 2 retries left"
level=info msg="retrying in 63 seconds (attempt 4 of 5)"
level=error msg="error while performing request: dial tcp 0.0.0.0:8080: connect: connection refused; 1 retries left"
level=info msg="retrying in 88 seconds (attempt 5 of 5)"

I don’t know if this can relate to the problem, but when checking the status of the docker I see this

in my case (crowdsec deployed as a docker compose stack with crowdsec app and docker bouncer) the bouncer installed on the docker host was not started correctly. this lead to restarts of the container.
after restarting the bouncer everything was ok again.
