Prometheus returned error “server returned HTTP status 401 Unauthorized” for .NET core api

[renjit...@gmail.com]

I have a .NET core api hosted in IIS which uses windows authentication. I'm using Prometheus to scrape metrics from this API. But I'm getting the error "server returned HTTP status 401 Unauthorized" for the api target. Can some help me how to configure prometheus for targets with Windows authentication?

When I tried to browse the metrics path separately, the browser is requesting for credentials and I'm able to view the metrics with my Windows authentication.

Currently Prometheus supports the following authentication methods: basic authentication, client certificate and bearer token.

I'm not sure that "Windows authentication" fits with any of these.
