Briefly, this error occurs when Elasticsearch is unable to monitor the directory for SSL configurations, possibly due to incorrect file paths, permissions issues, or the directory not existing. To resolve this, ensure the directory path in your Elasticsearch configuration is correct. Check the permissions of the directory and files, making sure Elasticsearch has read access. If the directory doesn’t exist, create it. Also, ensure that the SSL configurations are correctly set up. If the problem persists, consider disabling SSL or seeking further assistance.
