No coverage information available on sonarqube since last 3 weeks

Lines to cover on new code is coming as 0 for files which has some changes in it, because of this there is no code coverage getting reported for the new code. This used to get reported before 3 weeks but since then this issue is coming for all my repositories. I have attached screenshot which shows 4 files were changed but new lines on those files is 0.

Hi,

Welcome to the community!

0 lines to cover on new code means that no code changes were detected in the New Code period. Your changes have all been non-code, such as comments and whitespace.

 
HTH,
