Challenges with Configuring Confluent Replicator for Cross-Cluster Data Sync

Hello

I am facing an issue while setting up Confluent Replicator for cross-cluster replication between two Kafka clusters. The source cluster is on-prem; while the destination is hosted in a cloud environment. Despite following the official documentation, I encounter intermittent connection timeouts and replication lag. :upside_down_face:

I have confirmed that the necessary network configurations (firewalls, security groups, etc.) are in place.

Both clusters can communicate, and I can produce and consume messages from the source & destination clusters independently. However; during replication, the process sometimes stalls & logs show recurring connection errors with no clear resolution. :slightly_smiling_face: I have checked Cluster Replication - Confluent Community Java guide for reference but still need advice .

Has anyone faced similar challenges? Could this be related to specific configurations like offset translation, authentication issues (e.g., SASL/SSL) / even network latencies? :thinking:

Any troubleshooting tips would be greatly appreciated!

Thank you ! :slightly_smiling_face:

What do broker logs show at this time?
