It seems like you are federating through an ingress or load balancer that balances over multiple Prometheus server replicas. Either federate

As an alternative to the global federation, consider Thanos, it scales further and handles this situation out of the box.

Thank you. Will check this. This sounds right.

In official docs (https://prometheus.io/docs/prometheus/latest/federation/) there is an other federation config than I use

scrape_configs:
  - job_name: 'federate'
    scrape_interval: 15s

    honor_labels: true
    metrics_path: '/federate'

    params:
      'match[]':
        - '{job="prometheus"}'
        - '{__name__=~"job:.*"}'

Do I also need to modify that?

I use at the moment:

  - job_name: federate
    scrape_interval: 15s
    scrape_timeout: 15s
    honor_labels: false
    metrics_path: /federate
    scheme: https
    tls_config:
      insecure_skip_verify: true
    params:
        match[]:
          - '{__name__=~".+"}'

best regards
Evelyn
