List of Projects not visible on homepage after sonar 8.9 to 9.9 upgradation

Hi Team,

We recently did the SonarQube 8.9 LTS to 9.9 LTS upgradation along with the server migration from windows 2016 to windows 2019.

We were able to upgrade the sonar version successfully however we are not able to see the list of projects on the homepage which we were able to see earlier.

Currently we are able to browse through the list of projects using the Administration console.

It would be great if you can help guide us here.


Hi @Swapnil_Musrif,

Is the Sonarqube hosted in IIS, if yes, then the issue could be with the IIS being unable to handle the query length.
Please take a look at this reply here - SonarQube project page does not show any projects - #7 by julienlancelot, as I was facing the same issue and this helped me resolve it.
And this is the article I referred to increase the max query length - IIS: Changing maxQueryString and maxUrl | My Tec Bits.

Thanks Arvind.

Also, we are experiencing one more issue-

The Sonar project summary page shows the count of Bugs, issues, code smells but if we click on the count - it says empty.

@Colin - Could you please look into this and help with the project list and bugs count not visible issue.


@Colin - Could you please help here


Hi Swapnil,

Please don’t @ people not already involved in your thread. It doesn’t move you up the priority list; just the opposite.

Both of your symptoms point to corrupt Elasticsearch indices. Try:

  • stop your server
  • delete $SONARQUBE-HOME/data/es7
  • restart the server.
