Looking forward to your reply,
Did you make sure that you can open this link with the standard Android browser?
Is this only an Android issue or does it also occur on iOS?
Thanks for the reply, my Wikitude version is 5.2.0
Did I understood you correctly that you load the POI image resources over https or the entire Architect World?
In case it's about AR.ImageResources, did you try to implement the onError callback to check for potential error messages?
I'm using an html POI which contains an <image> tag and in that tag I'm using "https" image. For eg:
<image src="https://www.somesite.com/image.jpg" />
