Select Test Connection in step 2. Condense tries to reach the broker with the details you entered. Condense saves a connection after it has tested successfully.

​
What the test checks

  • NATS (embedded and self managed): Connects to the server, signs in, and reads basic information from your JetStream account. It gives up after about 5 seconds.
  • Condense Kafka Broker: Checks your credentials and reads the cluster information. About 3 seconds.
  • Confluent Cloud: Signs in and reads the list of topics. If you switched on Schema Registry it checks that too. About 8 seconds.
  • Apache Kafka (self managed): Opens a connection to the bootstrap servers, completes the TLS or SASL handshake and reads the cluster information. About 8 seconds.

​
If the test fails

The message tells you why. The two most common causes are the broker rejecting the credentials, and the broker not being reachable from Condense. See Troubleshooting for the messages and what to do.
