If you are using Confluence Data Center, we need a copy of the logs from all of the nodes in your cluster.If you have not yet filed a support ticket, file it at https://atlasauthority.atlassian.net/servicedesk/customer/portal/1/group/1/create/1
If you restart Confluence, this gets reset and you have to apply it again.
