Azure Application Gateway redirects to internal IP when used as a Reverse Proxy for Qlik Sense

[Sonja_Bauernfeind]

In a Qlik Sense Enterprise on Windows setup with an Azure Application Gateway as a reverse proxy, requests are falsely redirected to the internal IP.

To mitigate this, add the custom header "X-forwarded-Host" in the Azure Application Gateway, setting it to the external IP. 

See X-Forwarded-Host (external site) for more information regarding the custom header.

Environment

• Qlik Sense Enterprise on Windows 
• Azure Application Gateway

Hi Sonja,

Will this resolve the 502 error when the Azure Application Gateway backend protocol is set to HTTPS?

Also, how to make this "X-forwarded-Host" setting in the Application Gateway? What is the value?

Thank you,

Elbert

Hello @elbertfjr22 I cannot speak to the error you mentioned.

As for the value on X-forwarded-Host, as mentioned in the article, this should be the external IP address you intend to use.

All the best,
Sonja
