Thank you. NGINX is the only half of the story. Simply add “SonarQube” with that search string and my own post is the most relevant search result that relates to the 9.1 version. As a newcomer, I’m not sure if the version 7 is relevant to version 9. I couldn’t just assume that since I’ve been burnt with these kind of assumptions before. Moreover, your troubleshooting section seems to lack list of issues that one could face. Some are dead-end topics relevant to this (see example here)
Anyway, the issue is resolved. I was attempting to install on ubuntu 18.04 with NGINX. I switched to Windows installation and I’m up and running. It was a lot smoother. Thanks again.
