SONAR_HOST_URL variableThe sonar job uses ${{ vars.SONAR_HOST_URL }}. Make sure it points correctly:
http://<sonar-server-public-ip> (Nginx listens on port 80, default HTTP).The public IP changes on Stop/Start. If you just restarted SonarServer, grab the new IP, update
SONAR_HOST_URL, and wait ~5 minutes for SonarQube to start before raising the PR.
