Blank screen seen when logging into AppStreaming 2.0

Question

Hi, I am new to AppStreaming and am unsure how to troubleshoot this problem further so I hope that someone may be able to help.  When users of certain devices log into AppStreaming it presents them with the below blank screen.  It is not possible to click on any of the buttons on the toolbar at the top apart from the logoff button in the top right.

![Enter image description here](/media/postImages/original/IMglmLLumrQT-uw0Oivxye1g)

This used to work as expected for these devices previously and it works if another device is used instead by the same user that is connected to the same network.  There have been no configuration changes on the AWS side.  This issue presists when changing screen resolution settings and zoom settings in the Chrome browser.  The issue was first seen around 2 weeks ago.

Any help would be greatly appreciated.

Thanks.

Answer

Hi,

My name is Nonkululeko, from the notes, I understand that when users of certain devices log on AppStream is display a black screen.

This can happen if the application launch path is incorrect, and AppStream 2.0 can't launch the application. You can validate the application launch path by using Desktop View on the fleet to navigate the root volume. Validate that the application executable exists at the path specified.

If you're not able to find the app block's VHD or setup script on the streaming instance, AppStream 2.0 might not have been able to download them from the S3 bucket. Validate that the VPC you specified has access to S3. For more information, please see the attached link below.

I hope that you find the above information helpful
