How to gather application logs

In case, when we can not reproduce reported issue, we will ask you for application logs. We use this file to investigate what went wrong and if there is any trace of the error. Backend errors can be caused by Jira, our App, other 3rd party apps or scripts. In some cases you will have to contact your server administrator to investigate the problem.

For a better and faster support, please include it in support request.
