Kafka Connect with Strimzi template


I’m try to connect to my Confluent Cluster with KafkaConnect but the authentication failed. In the log I found:

“Connection to node -1 (***:9092) terminated during authentication. This may happen due to any of the following reasons: (1) Authentication failed due to invalid credentials with brokers older than 1.0.0, (2) Firewall blocking Kafka TLS traffic (eg it may only allow HTTPS traffic), (3) Transient network issue. (org.apache.kafka.clients.NetworkClient”

I created a KafkaConnect with Strimzi template to deploy in K8s. I set the authentication type as plain, username as key and password as secret.

I have not firewall and the telnet to my Confluent bootstrap server is ok.
