We've been having intermittent login issues in production and non-production. Our technical people have not been able to find the cause of the problem. It's not a network issue as far as we can tell. Our log shows error occurred while trying to authenticate user and the connection times out. Usually, we wait about 5 minutes and then we're able to log in. It seems to only happen with JIRA. Does anyone have any ideas what could be causing this problem?
