ticdc链接kafka报错

我这边升级了tidb到最新版本还是不行
./cdc cli changefeed create --sink-uri=‘kafka://172.21.0.9:9092/test?kafka-version=2.6.0&partition-num=1&max-message-bytes=67108864&replication-factor=1&protocol=canal-json’ --changefeed-id=“replication-task-2” --server=http://172.21.0.9:8300
Error: [CDC:ErrKafkaNewSaramaProducer]new sarama producer: dial tcp: lookup VM-0-9-centos on 183.60.83.19:53: no such host
这是报的错误信息,183.60.83.19:53这个ip也很诡异,并不在我的集群中
