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

[Sonja_Bauernfeind]

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
