Facing issues while sending Databricks Lineage (Spline) to kafka

Hi Team,
we have enabled spline on databricks cluster and we are able to connect from databricks to kafka using SSL certificate but spline is not able to connect to kafka that's why it is not able to send lineage to kafka & got below error .

SparkLineageInitializer: Spline successfully initialized. Spark Lineage tracking is ENABLED.
23/11/13 11:07:49 WARN NetworkClient: [Producer clientId=producer-1] Bootstrap broker xxxxxxxxxxxxx:9092 (id: -1 rack: null) disconnected
