3D Scene Layer fails to Load on WAB 2.5 with Proxy authentication

[BledarBirbo]

Hi.

As the title says the Scene Layer fails to load if a custom hosted Web Appbuilder Application is configured to work with a proxy with application credentials.

Everything in the 3D scene loads perfectly using the proxy, except for the Hosted Scene Layer. (point layer with 5000 features)

Any Idea what is going on ?

Thanks.

I also have the same problem did you find a solution ?
