You might run into the following problems when using Data Stream. Find out causes and possible solutions.

Data Stream connection error

Producer or consumer applications cannot connect to Data Stream.

Cause 1

Occurs when an incorrect broker address (TCP access endpoint) is set in the client application.

Solution

Make sure you have set the correct broker address (TCP access endpoint). The broker address (TCP access endpoint) can be checked through the NAVER Cloud Platform console and APIs.

Cause 2

Occurs when incorrect client authentication information (such as SASL/PLAIN certificates) is set in the client application.

Solution

Set the correct client authentication information (SASL configuration information) for each client type (Python, Java, Logstash). For more information, see Producer, Consumer.

Cause 3

Occurs when the client system's firewall does not allow outbound traffic to the broker address (TCP access endpoint).

Solution

Check the firewall settings on the client system and allow outbound traffic to the broker address (TCP access endpoint). The broker address (TCP access endpoint) can be checked through the NAVER Cloud Platform console and APIs.
