Dashboard "Loading"

I installed sonarqube 7.7 in amazon linux(EC2 instance). Installed MySQL 5.6
The dashboard shows “loading”

any help appreciated

Hello Paul,
Is there a specific reason why you installed the 7.7 version of SonarQube ? This one is not supported any more and new features were brought with the LTS and the Latest versions.
My first recommendation would be to install either the 7.9 or 8.0 and check if you still face the issue.
