Identify a DDS connection failure caused by a client problem from the following aspects.
- ECS Security Policy
In Windows, check whether the DDS port is enabled in the Windows security policy. In Linux, run the iptables command to check whether the DDS port is enabled in firewall settings.
- Application Configuration
Check whether the IP address, port parameter, and Java database connectivity (JDBC) are configured correctly.
