Error connecting to database

After looking at the issue further and many attempts to reconfigure my dbconfig.xml file we found that the localhost or dbserver id was configured incorrectly.  In the dbconfig.xml file it asked for a dbserver name id.  It isn't clear per instructions that it's the localhost if the MySQL server resides on the same system as the Jira application.   After providing the localhost ip and port info we were able to connect successfully.

Thanks for your feedbak

Seems like a connection issue. Might want to double check if the Confluence server are able to communicate with your database without any issue (Firewall or network issue).
