'Failed to construct kafka producer: No resolvable bootstrap urls given in bootstrap.servers (Intermittent issue)
I am getting intermittent issues while accessing the kafka service from the Kubernetes pod.

I am not sure which causes this issue intermittently as I've found the bootstrap urls are correct.
Solution 1:[1]
Its the Format of spring.kafka.bootstrap-servers=port:9092 sample: spring.kafka.bootstrap-servers=localhost:9092 or spring.kafka.bootstrap-servers=127.0.0.1:9092, etc
