Prometheus scrape job cannot reach the metrics

Support Self-hosting

Thanks @JammyDodger but unfortunately those resources didn’t help.

They have similar issue but slightly different to the point that they don’t apply in this case.
Just to be sure, I tried what one of those topics suggested (as well as @pfaffman) and played around with the DISCOURSE_PROMETHEUS_TRUSTED_IP_ALLOWLIST_REGEX env variable.

I tested:

  • Commenting it out
  • Added and with internal IP value
  • Added and with external IP value

Tried also changing the Prometheus scrape job to address the Discourse installation as:

  • direct internal IP
  • docker internal hostname
  • direct external IP
  • public domain name

In every case, tried both http and https

In all cases, I’m getting a 404.
What I would expect, is the actual page response as the request is coming from an internal IP.
