Blank tilemap

Hi.

Add the table Cities to your app. You can copy and paste the table using manual entry or you can import the table into your app using the web file connector.
In a sheet, add a map chart.
In Map settings, set Base map to None.
Add a background layer and do the following:
- In Data, do the following:
  - For Format, select TMS.
  - For URL, enter https://a.tile.openstreetmap.org/${z}/${x}/${y}.png.
  - For Attribution, enter © OpenStreetMap contributors.
- In Options, do the following:
  - Set Show legend to None.

Did all of the steps and I only got a blank screen. Attaching a screenshot.

Thanks in advance!

I tried it and I got the same issue.

You have to whitelist this external source. Check details here.

Go to the Management Console > Integration > Content Security Policy, and set it up like this:

Thank you @fosuzuki ! It worked! I am going to mark this as solved. However, I still couldn't get my tilemap to work. Here's the URL: http://v2.geoportal.gov.ph/tiles/v2/PGP/${z}/${x}/${y}.png.

I already whitelisted the source and followed your instructions. Still didn't work.

Again, thank you so much for your help!

I got this second url working on Qlik Sense Desktop, but not on QCS.

If you are paying for QS Business, I'd recommend you to raise a ticket and request help from Qlik support.
