Azure devops sonarqube integration is falling for .net project

Sonarqube version 6.7
Sonarcsharp 7.11

When we try to run analysis in azure devops to a remotly hosted sonarqube getting the below error.
Failed to request and parse ‘http://static/csharp/SonarAnalyzer-7.11.0.8083.zip’: Response status code does not indicate success: 503 (Service Unavailable)

Can you please check for service connection in azure devops and also whether the relevant ports are opened for communication on the remote server?

Hi,

Welcome to the community @Harishgs!

SonarQube 6.7 is far past EOL. The current LTS is 7.9, the current version is 8.9 and the new LTS (8.9) is imminent. You should upgrade immediately. Depending on whether you upgrade before or after 4 May (anticipated LTS release date) your upgrade path is one of:

6.7 → 7.9.6 → 8.8 (last step optional)

or

6.7 → 7.9.6 → 8.9

Regarding your error, a 503 response code indicates a server error. If you see nothing in your server logs then you should talk to the maintainers of your network proxy to see why/how this is being blocked.

 
HTH,
