AKHQ can't connect to kafka brokers - authentication failed.

Any ideas what's missing here?

2023-01-04 10:13:57,211 WARN  inclient-1 o.a.k.c.NetworkClient      [AdminClient clientId=adminclient-1] Connection to node -1 (default-kafka-headless/10.0.21.162:9092) 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.

My helm configuration is like this:

configuration:
      akhq:
        connections:
          <cluster>:
            properties:
              bootstrap.servers: "default-kafka-headless:9092"
              security.protocol: SASL_SSL
              sasl.mechanism: PLAIN
              sasl.jaas.config: org.apache.kafka.common.security.plain.PlainLoginModule required username="<user>" password="<pass>";
            schema-registry:
              url: "<URL>"

Thanks.

Solved.
Can be closed.

The issue was with security.protocol: SASL_PLAINTEXT # SASL_SSL If it helps someone.
