    msg: >-
      Trying to append prometheus-nginxlog-exporter's configuration to matrix-nginx-proxy,
      but it's pointless since the matrix-nginx-proxy role is already executed.
      To fix this, please change the order of roles in your playbook to make sure that
      the matrix-nginx-proxy role is run after the prometheus-nginxlog-exporter role.
