Background layer in map not working... why?

[gilbo]

I followed the instructions in this official link: https://www.youtube.com/watch?v=hml7wX4O7Lw&t=65s&ab_channel=QlikHelp  with no luck. 

When I add the image and the coordinates as the video indicates (up to minute 1:00) I see no image... just text indicating that an image should be there.

This forum https://community.qlik.com/t5/App-Development/Map-background-Image-not-loading/td-p/1779812 indicates there is a problem with IP whitelisting, but I cannot find where to whitelist an IP. 

Is that the problem (IP whitelisting) or is it a bug... or what is it? I really want to use this product. It is ideal for a client, but this heatmap visualisation is a requirement.

Thank you for your support

Hello,

This could be related to multiple issues. Here are some troubleshooting steps that might help you resolve the issue:

1. Check if it is related to CORS: "Mixed Content and CORS error for Access-Control-Allow-Origin" [1]
   1. You can hit F12 on your keyboard, while accessing your app though Chrome and it will give show you if there are any errors in Developers Console. Those errors might help you by pointing you to the right direction.
2. Try using a different image, from a different server. Such as: https://upload.wikimedia.org/wikipedia/commons/b/b6/Image_created_with_a_mobile_phone.png
3. Try using the same image, but instead using https, use http. 
   1. For example, instead of using an image as: https://cdn.pixabay.com/photo/2016/10/18/21/22/beach-1751455_960_720.jpg
   2. Try using http://cdn.pixabay.com/photo/2016/10/18/21/22/beach-1751455_960_720.jpg
   3. I have tried using both links and it worked on my side.
4. Try using a newer version of Qlik Sense, if you are not already using one. (You have added the tag Qlik SaaS, however the links that you share refer to Qlik Sense.) Are you using Qlik Sense or Qlik SaaS after all? 
5. If the image is not found (link broken etc.) or unable to load, you should see the default map layout instead of a white background. Maybe you can try:
   1. Changing the values Top, Left, Bottom, Right
   2. Scaling the chart
   3. Try using Qlik Sense on a new machine and connected to a different network. (Network or machine configuration, might be blocking proper access)

If none of the steps above helped point you to the right path, you can share new screenshots for each step, so we could see if there are any logs or error messages in the Developers Console or if anything changes in the behavior of each step.
