I recently started having issues with JIRA redirecting all requests to '/secure/errors.jsp.' I'm not entirely certain what may have changed on the server that led to the issue because there are several things I use the server for.
On investigation of the logs, I see that the below error and stack trace show up on startup. The strange thing is that my JIRA instance is configured to use postgres rather than mysql, so I'm not certain why it's trying to do a Mysql health check.
I've tried deleting the '.bundled-plugins' and '.osgi-plugins' directories as recommended in other topics, but no luck.
Can anyone point me in a direction of something to try next?
