Hi Jakob, The consumer is not consuming the messages because the messages might have already been consumed using the consumer group, jupiter-workers. So, the options below will help you read the messages.
1. Change the group.id from jupiter-workers to something else like jupiter-workers-latest 2. Reset the consumer offset of the consumer group "jupiter-workers" of Topic "jupiter-events" to the beginning offset, and then start the consumer application Please reach out if any more details are needed.
