Able to connect successfully to local kafka broker/cluster running locally (dockerized) using Conduktor, but when trying to connect to Kafka cluster running on Unix VM, getting below error. Error: "The broker [...] is reachable but Kafka can't connect. Ensure you have access to the advertised listeners of the the brokers and the proper authorization"
Appreciate any assistance.
running locally (dockerized)
When running in docker, you need to ensure that the ports are accessible from outside of your container. To verify this, try doing a telnet <ip> <port> and check if you are able to connect.
Since the error message says, the broker is reachable, I suppose you would be able to successfully telnet to the broker.
Next, check your broker config called advertised.listeners. Here you need to mention your IP:Port combination where IP is what you will be giving in your client program i.e. Conduktor.
An example for that would be
advertised.listeners=PLAINTEXT://1.2.3.4:9092
and then restart your broker and reconnect. If you are using ssl then you need to provide some extra configuration. See Configuring Kafka brokers for more.
