Hi All,

I am using kamon-prometheus (version 2.1.3) to send metrics to prometheus pushgateway.
I got issue that the message always empty. Here is my configuration

prometheus {
    start-embedded-http-server = no

    include-environment-tags = yes

    pushgateway {
      api-url = "http://stg-xxxx"

      connect-timeout = 5 seconds
      read-timeout = 5 seconds
      write-timeout = 5 seconds
    }

    metric {
      tick-interval = 1 seconds
    }

  }

This is the error message:

[2020-09-23 16:41:00,128] ERROR Failed to send metrics to Prometheus Pushgateway (kamon.prometheus.PrometheusPushgatewayReporter:44)
