I keep getting the error of ERROR: SonarQube server [***] can not be reached, I would like to find where I can find the value of sonar_host_url if you are running sonarqube on your github action and not locally.
I am also getting the error

Caused by: java.lang.IllegalStateException: Fail to get bootstrap index from server

and Caused by: java.net.UnknownHostException: qa.xxx.com: Name does not resolve

please let me know how I can get rid of all these errors, my workflow.yml is as follows:

  # Trigger analysis when pushing in master or pull requests, and when creating
  # a pull request.
  push:
    branches:
      - '*'

Hey there.

Are you intending to target https://sonarcloud.io – or a self-hosted SonarQube server?
