How Do I Do If I Cannot Connect to a GaussDB(DWS) Cluster?
Possible Causes
Check the following:
- Whether the cluster status is normal.
- Whether the connection command, username, password, IP address, and port number are incorrect.
- Whether the operating system type and version of the client are correct.
- Whether the client is incorrectly installed.
If cluster connection failed on the public cloud, check for the following as well:
- The ECSs are not in the same AZ, VPC, subnet, and security group as the cluster.
- Some of the inbound and outbound rules of the security group are incorrect.
If cluster connection failed through the Internet, confirm the following:
- Whether your network is connected to the Internet.
- Whether the firewall blocked the access.
- Whether you need to access the Internet through a proxy.
