Logstash rabbitmq input plugin doesn't read "host" value

[thinkorhiking]

I'm having trouble to setup logstash rabbitmq input plugin, to connect to the rabbitmq pod host name.
Why it still tries to connect @localhost. logstash does not read the config correctly. Is this a bug or is there any workaround ?
Logstash version: happens on both 6.8.22 and 7.17.3.
I already have tried everything suggested in internet, but it didn't work.

logstash.conf: |
    input {
      rabbitmq {
        host => "rabbitmq:5672"
        vhost => "/"
        ...
        exchange => "amq.rabbitmq.trace"
        key => "#"
      }
   }
}
