Resolution

1. In the js.quartz.properties file, please defined the correct mail host name value to the report.scheduler.mail.sender.host property.
report.scheduler.mail.sender.host=smtphost.example.com
Also, confirmed that the report.scheduler.web.deployment.uri property is defined correctly.
report.scheduler.web.deployment.uri=http://example.com/reportservice/

2. Next, in the js.config.properties file, please confirmed that the deploy.base.local.url is defined correctly.
deploy.base.local.url=http://example.com/reportservice/
If the deploy.base.url was previously defined with an error in the URL. please now defined the correct URL for the same.
deploy.base.url=http://example.com/reportservice/

3. Finally, in the applicationContext-report-scheduling.xml file, Please check that the mail.smtp.auth property is defined as true. The smtp.starttls.enable was defined as true in this file, but the same property was defined as false in the js.quartz.properties file. Also please confirm with your mail server admin, and this property needs to be false for your environment.

4. After saving all the changes, Please restart the Tomcat.

5. Schedule the Test Report
