What is the purpose of the Service listen port in Qlik Sense?

The service listen port in Qlik Sense serves as the entry point for HTTPS requests from clients to the proxy server, which is crucial for secure data exchange. This port enables authentication and communication between users and the Qlik Sense ecosystem, ensuring that client requests are processed over a secure connection.

When clients send requests, whether for accessing the user interface or for data loading and visualization, these requests are routed through the proxy server, which listens on this designated port. This setup maintains the security and integrity of the data as it travels over the network, making it a fundamental component for the operation of Qlik Sense in a secure environment.

Considering the other options, while REST API requests, Kerberos authentication requests, and data load scripts are important features within Qlik Sense, they are not specifically tied to the service listen port in the same way that HTTPS requests are. The focus of the service listen port is primarily on facilitating secure communication between the client and the proxy server, distinguishing it from the other functionalities mentioned.
