Brokers are down error while trying to deploy a log file onto kafka topic using Fluent-Bit_Config

I changed fluent-bit-config and put the file from where it has to read in

The IP in the Broker I have used is my local Kubernetes environment's Kafka service, But it gives error of ** brokers are down. Disconnected while requestng ApiVersion: might be caused by incorrect security.protocol configuration ( connencting to a ssl listener?) or broker version<0.1)

enter image description here

Am I using Kafka service correctly as a broker? or is there something else I should put in the broker?
