Ports overview

The following figure provides an overview of the ports that are used in a default Qlik Sense installation.

The superscript numbers in the figure refer to the following:

  1. The Authentication (ticket) API in the Qlik Sense Proxy Service (QPS).
  2. The Session API in the QPS.
  3. For example, a Single Sign-On (SSO) portal that uses the Session API.
  4. This port is used when the slave Qlik Sense Scheduler Service (QSS) is located on the central node in the site.
  5. This port is used when the slave QSS is located on a rim node.

The following table provides details on the ports in the figure.

Port Description
80

Optional Qlik Sense Proxy Service (QPS) listen port.

This port uses HTTP for communication.

Information noteThis port is only available when client-side HTTP communication is enabled. This is managed in the Qlik Management Console (QMC).
443

Default Qlik Sense Proxy Service (QPS) listen port.

This port uses HTTPS for communication.

Tip noteMake sure that port 443 is available for the QPS to use, since the port is sometimes used by other software (for example, web servers).
4239

WebSocket server port. This port exposes parts of the Qlik Sense Repository Service (QRS) API over WebSocket.

This port uses HTTPS for communication.

4241

Communication port within multi-node sites for Qlik Sense Repository Service (QRS)-to-QRS synchronization.

This port uses HTTPS for communication.

4242

Qlik Sense Repository Service (QRS) REST API listen port. Also used by the QRS configuration service for the node registration process before the QRS API service is made available.

This port uses HTTPS for communication.

4243

Qlik Sense Proxy Service (QPS) REST API listen port.

4244

Default Qlik Sense Proxy Service (QPS) authentication listen port. This port is used by the internal authentication module in the QPS when using NTLM in Microsoft Windows.

4432

Default listen port for the Qlik Sense Repository Database (QRD). The port is used to listen for connections from the Qlik Sense Repository Service (QRS).

In a default Qlik Sense installation, the Qlik Sense Repository Service (QRS) uses the Qlik Sense Repository Database (QRD) service to read and write data in the repository database. A PostgreSQL database is used by default.

4444

This port has two functions:

  • Security distribution port, only used by Qlik Sense Repository Services (QRSs) on rim nodes to receive a certificate from the master QRS on the central node. The communication is always unencrypted, but the transferred certificate package is password-protected.

  • Qlik Sense Repository Service (QRS) state port, used to fetch the state of a QRS in a Qlik Sense site. The state is fetched using http://localhost:4444/status/servicestate.

    The returned state is one of the following:

    • 0: Initializing. Once the node has been initialized, the node state changes into one of the other states.
    • 1: Certificates not installed. There are no certificates installed on the node. The node stays in this state until it has received the certificate and the certificate password.
    • 2: Running. The node is up and running and all APIs have been initiated.
4545 This port is used by the Migration Service for app migration purposes. The service is launched and managed by the Qlik Sense Service Dispatcher (QSD).
4555

This port is used by the Chart Sharing Service for chart sharing between Qlik Sense users. The service is launched and managed by the Qlik Sense Service Dispatcher (QSD).
