Read message from UI but got 400 Bad Request

[Zeeeeta]

I have a single node Kafka (kafka_2.13-3.3.2.tgz) cluster running on a Linux server (no internet).
It is a default setup using KRaft and the only config I have set is the /config/kraft/server.properties: advertised.listeners=PLAINTEXT://192.168.20.109:9092, where 192.168.20.109 is the LAN IP.

I am using UI for Apache Kafka v0.5.0 (027d9b4) running locally on my PC on port 8080, directly from Java without using docker.
application-local.yml as below:

kafka:
  clusters:
    - name: "[UAT] Kafka"
      bootstrapServers: 192.168.20.109:9092

Only port 9092-9093 firewall rules opened between my PC and the server.

I created a test topic using the UI, and produced some test message.

However, when I try to view the message using the UI, it still shows no messages found and when I check the API call, the response is 400 Bad Request.

May I get some help on what the problem could be?
Thanks.

Hi, can you verify that it works fine with any other cluster without special symbols ([,], )?

Oh it worked, thanks for the help.

Glad it works! Probly we encode the cluster name the wrong way
