自行生成的证书，启用了https后，es8无法生成口令

./bin/elasticsearch-create-enrollment-token -s kibana --url "https://172.16.8.8:9200"

提示

ERROR: Unable to create an enrollment token. Elasticsearch node HTTP layer SSL configuration Keystore doesn't contain any PrivateKey entries where the associated certificate is a CA certificate
