sonar cube local host is not working in ubuntu 20.04

[manjugb]

I completed Sonarqube installation but web page is not accessible. I tried localhost i.e http://localhost:9000 on browser but it does not display any pages. Any feedback will be great help.

here is the steps i followed using this link https://www.fosstechnix.com/how-to-install-sonarqube-on-ubuntu-20-04/

active service is running and i am not able to access through http://localhost:9000
here is the config file
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar
sonar.jdbc.url=jdbc:postgresql://localhost:5432/sonarqube
sonar.web.host=0.0.0.0
sonar.web.port=9000
sonar.web.javaAdditionalOpts=-server
sonar.search.javaOpts=-Xmx512m -Xms512m -XX:+HeapDumpOnOutOfMemoryError
sonar.log.level=INFO
sonar.path.logs=logs

here is the auto service activation status
