Hi Team I hope you are doing well.
Actually i tried to installed Sonar 7.8 but getting connection refused error.
I installed open jdk 11 on one of my server and tried with that, but no success.
With same configuration with jdk 8 sonar 5.0.1 is working fine on same server.
please see the logs as well–>
