Briefly, this error occurs when Elasticsearch is unable to find a private key for a specific credential. This could be due to incorrect configuration or the key might be missing or inaccessible. To resolve this issue, you can check the Elasticsearch configuration files to ensure the correct path to the private key is specified. If the path is correct, verify that the private key file exists at that location and Elasticsearch has the necessary permissions to access it. If the key is missing, you may need to generate a new one.
