When I try to connect with PLAINTEXT, it is connecting , however, when I try connecting through SSL port 9093, I am getting the following error (unable to list topics)
Error while executing topic command : The AdminClient thread has exited. Call: listTopics

The command I am using is
./kafka-topics.sh --list --bootstrap-server localhost:9093
Not sure. Also, “Kafka Streams” seems not to be the best category for this question. Maybe try “tools” or “ops” ?
hey @Kopal
seems like a known bug which could happen when ssl config on client is not properly.
how did you configure your client to connect to secure cluster?
