What Should 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.
