Hi, I’m trying to get Pixel Streaming working with Unreal Engine 5 on an AWS instance; I’ve mainly been using the tutorial videos found [here](https://www.youtube.com/watch?v=gkqZe5OMlj4&list=PLOYtv5sEWAuPzqVKfwIAiJqRsqBCd6K-a). I was able to get an instance working locally and on an AWS EC2 instance, but every time I try to connect with a mobile device the Unreal application crashes. I’m wondering if anyone else has had similar issues and had any experience troubleshooting. Thanks!

I’m packaging the UE5 project in Windows

and running(PixelStreaming) in Amazon Web services instance with public IP

it runs smoothly in all web browsers (Only PC),

When I tried to open that link(Public Ip) in a mobile browser it is crashing with this error

Hello. I have the same problem. I’m using UE 4.27. I start the streaming and my game on the server, and it works all right if I open it from a PC. If I open it from a mobile device, the game shows my starter widget which covers all the screen, but after I click something and the widget has to disappear, the game crashes on the server.

Has anybody found a solution yet?
