Nifi does not read data from the topic KAFKA on the SASL_SSL port.

There is a Quorum Kafka cluster with parameters.

 

 

listeners=PLAINTEXT://:9092,CONTROLLER://:9093, SASL_PLAINTEXT://:9094
security.inter.broker.protocol= SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
allow.everyone.if.no.acl.found=true
super.users=User:admin
advertised.listeners=SASL_PLAINTEXT://:9092, PLAINTEXT://:9093

 

 

Here you can see that port 9094 is set to SASL_PLAINTEXT.

In nifi, I can write to a topic using the PublishKafka_2_6 processor, using port 9094.

But it is impossible to read from the same topic and port 9094. The processor does not show any errors. I used different versions of the consumekafka processor. No results.

I am able to read from the topic on the insecure port 9092. I am also able to read on the SASL_PLAINTEXT port through other tools such as datagrip. But for some reason nifi does not want to read through this port. help me please.
nifi version 1.16.3

Thank you for the answer. Indeed, the problem was in the configuration on one and the nodes. Port was not specified. I was confused by the fact that through third-party tools I could read from the topic.
