Currently I am using kafka_2.12-2.5.0 with Java Service (Spring-boot). I used to start zookeeper kafka and then debezium services first and they used to run successfully. After that If I try to run java service then kafka service is going down within some time At That Time Debezium Showing these logs continuously :
[2020-10-09 06:45:58,503] WARN [Producer clientId=connector-producer-sql-server-connection-0] Connection to node 0 (vsi-kafka-dev-01.c.presence-ss.internal/10.128.15.238:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient:762)
And At the same time Java service showing these logs continuously :
