What Should I Do If I Cannot Connect to a Data Warehouse Cluster?

Troubleshooting

Check:

• Whether the cluster status is normal.
• Whether the connection command, username, password, IP address, and port are correct.
• Whether the operating system type and version of the client are correct.
• Whether the client is properly installed.

If cluster connection failed on the public cloud, check the following items:

• Whether the ECSs are in the same AZ, VPC, subnet, and security group as the cluster.
• Whether the inbound and outbound rules of the security group are correct.

If cluster connection failed through the Internet, confirm the following items:

• Whether your network is connected to the Internet.
• Whether the firewall blocked access.
• Whether you need to access the Internet through a proxy.
