Getting connection refused when using kafka-ui-auth-context.yaml

[jonbon-doe]

Hi,

I am trying to run the kafka-ui-auth-context.yaml which is provided in the documentation at documentation/compose/kafka-ui-auth-context.yaml.

I wanted to test this docker compose before making any changes and deploying but when I run this docker compose I am getting the following error:

Hi, this looks like an invalid host somewhere in advertised listeners.
