Can anyone help me on this issue?


It’s not the access log that will help you here. Take a look at the Troubleshooting documentation.


Thanks for the reply, Ann.

The problem is, when I click “Send Test Email” button and observed above error issue, only access.log has update, other log files in your troubleshooting page has no message output at all. Could you help?

In simple ask, which special points I need to take care of if I need to send email notification from sonarqube, I’ve check all configuration from document regarding email notification on sonar but still not works. By the way, I use smtp server, and confirmed sonarqube instance is able to connect with that smtp server.


I really don’t know what else to tell you. The first step is to make sure SonarQube can send that test email to/via your SMTP server, and with no error logs, it’s going to be impossible to help you diagnose this remotely.
