        dbname='sakila', host='ec2-55-231-255-3.compute-1.amazonaws.com',port=1234)

Answer 1

您可能需要转到“安全组”，并将本地IP地址添加为允许的“入站”连接。

Amazon Webservices Dashboard > Networking > VPC > Networking and Security > Security Groups > Inbound (tab)

Answer 2

You need to add inbound IP of EC2 security group of EC2 instance/ machine. but How ??

1. Go to EC2 service and select the instance you are using
2. In description you can see "Security groups"
3. Select the security group, it will open another page, which shows of the name and property of that same security group.
4. Select inbound from bottom panel and add your local machine IP address into inbound
