I have a single strimzi kafka cluster running on minishift deployed with default template values. I get no errors when zookeeper starts. The client is a spring boot application but cannot send messages to kafka topic.
These are spring boot application logs:

Spring boot application is also deployed on openshift cluster in the same project where kafka is deployed.
Any ideas?
I'm using spring boot 2.7.0
minishift 1.34
strimzi 0.22.1
