SonarQube Analyze Error - "server can not be reached"

I’m running Sonarqube task in azure devops pipeline. But SonarQube analyze task is being failed with error.
##[error]ERROR: SonarQube server [] can not be reached.

While “” is working fine in browser. I have only blocked login page from internet.
Can someone please help here. I have uploaded azuredevops error logs.
