Remote-write to Newrelic works if it is stopped

General Help/Support

Hi
Sorry for long question, but I try to describe the situation.
I’m not an expert in Prometheus but I’ve got a task to decrease amount of metrics that prometheus are sending to Nerwrelic by remote_write.
I use Quay in my infrastructure.

I have special config for remote-writes where metrics divided into groups. Each group has specific regexp like:

      - url: someurl
        name: groupname
        bearerToken: mybearertoekn
        writeRelabelConfigs:
          - sourceLabels: ['__name__']
            regex: ^metric_.*
            action: keep

I removed some groups from config, applied it to prometheus but still see that metrics are going to Newrelic.
Of course I looked into the prometheus config - there is no section that I’ve deleted.
Also after applying in the prometheus logs I see that remote storage was stopped:

I tried to delete/recreate pod with prometheus to apply new config to the new pod - but situation is the same.
Tried googling such problems but met only reverse task, like “my remote-write does not pass data to remote storage”.
How is it possible?
What I need to analyze to investigate this issue further?
Thank You
