Hi Che!

Sorry to hear your Confluence instance isn't starting up! The "Unable to rollback against JDBC Connection" error you're seeing typically indicates an issue connecting to the database, but it can have a number of different causes (e.g. no network path to database, bad database driver, database is down, etc.).

To help us better understand the issue:

• What version of Confluence are you using?
• What database type and version are you using?
• What steps did you take to stop Confluence before you started seeing the issue?
• What steps did you take to start Confluence?
• What changed (if anything) since the last time you successfully ran Confluence?
• Are you able to connect to the database directly? (e.g. via command line or third-party database connection tool)

In the meantime, I also found a few other related Community Questions and articles that might help you troubleshoot:

• Caused by: net.sf.hibernate.TransactionException: Unable to rollback against JDBC Connection
• Getting the error "Confluence had problems starting up"
• Problem with starting Confluence/Jira
• Unable to startup Confluence with java.net.ConnectException

Thanks!
