What is the function of port 4241 within Qlik Sense architecture?

Port 4241 is primarily used for communication related to QRS-to-QRS synchronization in multi-node environments within Qlik Sense architecture. This functionality is crucial in multi-node deployments where multiple Qlik Sense nodes (servers) must maintain consistent and synchronized data related to app management, user authentication, and other central repository tasks. This port ensures that information and state are shared accurately across different nodes, facilitating efficient load balancing and failover capabilities.

In contrast, other options represent different aspects of Qlik Sense communication. For instance, the Qlik Sense Proxy Service operates through a different designated port; each service within Qlik Sense architecture has specific ports allocated for its unique responsibilities. Similarly, the WebSocket server responsible for repository API communication and the default HTTP communication for Qlik Sense use different ports as well. Understanding the role of these ports is key for effective system administration and troubleshooting in Qlik Sense environments.
