Node exporter full dashboard not working after relabeling

I am trying to import and use the full node exporter dashboard.

I am using ec2 autodiscovery on prometheus since I am monitoring some AWS instances; my configuration is the following:

  # EC2 Jobs
  - job_name: 'ec2-nodes'
    ec2_sd_configs:
      - region: eu-west-1
        access_key: XXXXXXXXXXXXXXXXXXX
        secret_key: XXXXXXXXXXXXXXXXXXXXXXXXX
        port: 9100
    relabel_configs:
      - source_labels: [__meta_ec2_tag_Monitored]
        regex: PrometheusProduction.*
        action: keep
      - source_labels: [__meta_ec2_private_ip]
        regex:  '(.*)'
        target_label: __address__
        replacement: '${1}:9100'
      - source_labels: [__meta_ec2_tag_Name]
        regex:  '(.*)'
        target_label: instance
        replacement: '${1}'

I have tried to use __address__ in the place of node in the variables section, but with no luck.

Is this an issue with my relabeling?

Thx.
