Sonarqube scanner step failing in Jenkins job

Hi, all.

Hope you are okay.

Sonarqube scanned failing to scan specific projects. Most likely happened, when two different sonarqube hosts ( same vesion - 9.7.1 ) have been accidentially connected to the one DB server ( external ) in during ansible playbook testing.

There was about 4 days of time, for the project to be re scanned - it did not help.

Sonarqube log files looks okay - at least there is not any specific errors / failed steps

In jenkins output

[WARNING] Using an unspecified version instead of an explicit plugin version may introduce breaking analysis changes at an unwanted time. It is highly recommended to use an explicit version, e.g. ‘org.sonarsource.scanner.maven:sonar-maven-plugin:5.1.0.4751’

tried different version of the scanner - no luck.

Any ideas what can be done / where to have a look.

Kind regards,

Seems all sorted, by restart sonarqube service.
