I would recommend that you contact your support who is responsible for further troubleshooting. They will have access to specific tools that may be able to help identify the cause of the issue (after giving them the Logs). It's also important to note that the support team will have a better understanding of your specific environment and any customizations or configurations that may be impacting the issue.
