How to configure network load balancer (NLB) with Qlik Sense Enterprise on Windows

Sonja_Bauernfeind — Wed, 26 Nov 2025 08:40:43 GMT

Qlik Sense Enterprise on Windows supports network load balancers (NLB) for distributing user sessions over multiple Qlik Sense Proxies.

A successful load-balancing setup requires that the load balancer meets the Qlik Sense basic communication requirements:

Open ports
Support for the WebSocket protocol
Sticky/persistent sessions
Session timeout

Qlik Sense does not deem specific network load balancers supported or unsupported, but requires that a load balancer's behavior comply with the Qlik Sense traffic requirements. See Network Load Balancer (NLB) With Qlik Sense Enterprise April 2018 and later for more details.

Qlik Support cannot assist in configuration and setup.

For configuration and setup assistance:

Network load balancer vendor provided support channels
Network load balancer documentation
Configuration advice from other Qlik customers through the Qlik Community
Network load balancer configuration through Qlik Professional Services, see How and when to contact Qlik's Professional Services and Consulting Teams? for more details
