Error when there are multiple brokers

I have specified 3 bootstrap servers and when I checked from Kafdrop web console, there are 12 brokers.

I managed to serve Kafdrop in my local PC. When I click a certain topic, an exception named ClusterAuthorizationException occurred, but I can see the topic description and it's contents.

Error message:

Caused by: org.apache.kafka.common.errors.ClusterAuthorizationException: Request Request(processor=5, connectionId=10.117.148.62:11498-10.99.179.97:56717-2951640, session=Session(User:abc-1,10.99.179.97/10.99.177.97), listenerName=ListenerName(SASL_SSL), securityProtocol=SASL_SSL, buffer=null) is not authorized.

I successfully ran bin/kafka-console-consumer.sh to consume message from my Kafka server.

Kafka config:

security.protocol=SASL_SSL
ssl.endpoint.identification.algorithm=
ssl.truststore.location=/opt/kafka.client.truststore.jks
ssl.truststore.password=xxxx
sasl.mechanism=SCRAM-SHA-512
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required \
  username=abc-1 \
  password=xxxxxxxxxx;

.env: KAFKA_BROKERCONNECT="10.117.148.62:11498,10.117.148.61:11498,10.117.148.63:11498" KAFKA_PROPERTIES="BASE64 of my config file" JVM_OPTS="-Xms16M -Xmx48M -Xss180K -XX:-TieredCompilation -XX:+UseStringDeduplication -noverify -Dcom.sun.net.ssl.checkRevocation=false" SERVER_SERVELET_CONTEXTPATH="/"

It takes time, but I can get the messages from the console:
