I am getting below issues while accessing SSRS. Can anyone let me know if you have faced this issue before.
The RSReportServer.config file has been modified.
Report ServerWindows Service (MSSQLSERVER) cannot connect to the report server database. The value for UrlRoot in RSReportServer.config is not valid. The default value will be used instead.

I clicked the "test connection" button in the Reporting Services Configuration Manager and it succeeds.
