I get the following error when trying to load PNG (more https) in an iframe on an Amazon mechanical Turk:
SEC7117: Network request to https://toucan.cs.colostate.edu/pp/images/125.png did not succeed. This Internet Explorer instance does not have the following capabilities: privateNetworkClientServer
You can view the page here https://workersandbox.mturk.com/mturk/preview?groupId=36TBNKR908TLAX7SKNTTRWW7TFYEDT It works great in all other browsers.
I can’t understand for life why Edge will block PNG files (I can understand JS) and how to fix it. Any ideas would be greatly appreciated.
Additional information
Windows 10 64bit
Edge 20.10240.16384.0
Tested on several machines and were able to reproduce the problem
They have administrator rights on all machines and they are not part of the domain.

It seems that the problem is with the web server hosting the image on which Apache is running. I put the image on another Apache server and everything worked fine. so I tried to send the CORS header for all the images as described in https://github.com/h5bp/server-configs-apache/blob/fc379c45f52a09dd41279dbf4e60ae281110a5b0/src/.htaccess#L36-L53
but this still did not solve the problem. For some reason, Edge blocks the request.
