@NceAirport do you have a minimum required configuration?
As I see it should be something like:

set service monitoring xxx prometheus authentication login xxx
set service monitoring xxx prometheus authentication password xxx
set service monitoring xxx prometheus port 9273
set service monitoring xxx prometheus network 192.0.2.0/24

and conf:

[[outputs.prometheus_client]]
  listen = ":9273"
  basic_username = "xxx"
  basic_password = "xxx"
  ip_range = ["192.0.2.0/24"]

Viacheslav changed the task status from Open to In progress.May 2 2022, 12:51 PM
