I have set up Kafka on my server and it is running:
kafka.service
Loaded: loaded (/etc/systemd/system/kafka.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2022-09-13 13:24:47 CEST; 20min ago
Main PID: 5057 (sh)
Tasks: 80 (limit: 76840)
Memory: 397.7M
I can add Topics and Messages via the console and also consume them.
I am running this Docker container: https://hub.docker.com/r/provectuslabs/kafka-ui
The Dashboard is available through my URL but the Cluster is not connected. I get the following error:
Connection to node -1 (/127.0.0.1:9092) could not be established. Broker may not be available.
I am not sure what to make of this. What exactly did I configure wrong?
