From my central admin, manage servers, i could able to see my server but Config cache is not getting updated even though the timer server and SharePoint admin server is started.
When i checked the eventviewer logs, i found below 2 errors.
Database 'SharePoint_Config' on SQL Server instance 'SPSQLServer' is not empty and does not match current database schema
SharePoint object [SPConfigurationDatabase] is in an unsupported state, and could not be used by the current farm.
