Web Browser Widget not Supporting WebGL

I am using the web browser widget to display some WebGL content, but for some reason, when I go to http://get.webgl.org/ I get a message saying that WebGL is disabled or unavailable.


This same website (or any other website using WebGL) works perfectly fine on any other browser I use. I tried this with Unreal Engine versions 4.27.1, 4.25.4, 4.24.3, and 4.23.1.

This same setup seems to work with a colleague of mine (on a different machine) but also running Unreal Engine 4.25.4.

Is there a specific setting I need to activate to enable WebGL on the web browser widget? Is there something I am missing?

Just in case someone else runs into this issue. It turns out that the reason is because I was using Remote Desktop Connection to access this PC, and apparently hardware acceleration is disabled by default in RDP connections by group policy.
