从Mac连接到AWS EMR群集时出错

我正在尝试创建3节点的AWS EMR集群。我还创建了一个密钥,通过命令从MacOS连接到集群:

ssh -i ~/Downloads/BigdataKey.pem hadoop@ec2-xx-xx-xx-xx.ap-south-1.compute.amazonaws.com

但它给出的错误是:

192:Downloads nageshsinghchauhan$ ssh -i ~/Downloads/BigdataKey.pem hadoop@ec2-xx-xx-xx-xx.ap-south-1.compute.amazonaws.com
ssh: connect to host ec2-xx-xx-xx-xx.ap-south-1.compute.amazonaws.com port 22: Operation timed out

任何人请帮助我,我是第一次使用MacOS。
