but after upgrading the protocol from http to https

CodePudding user response：

Kafka isn't an HTTP protocol, so your problem has nothing to do with that

You've set KAFKA_BOOTSTRAPSERVERS=kafka:9092

i did not change any configuration about Kafka

I think you did. That IP address is not the default of anything. To revert to expected behavior within the same Docker network, you need to set

LISTENERS: PLAINTEXT://0.0.0.0:9092
KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092

Unclear where you're getting the IP address from, but if you want to expose the Docker container to an external network in that subnet, then you will need other settings
