AppStream2 User gets Blank Screen

Question

I am completely new to AppStream and AWS having used MS Azure for everything up until now.

Today I created an application using Elastic Fleet in AppStream2. I created a VHD file, uploaded it to a new S3 bucket and set JSON permissions from a document to allow the service to see the VHD file and script:

```
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowAppStream2.0ToRetrieveObjects",
            "Effect": "Allow",
            "Principal": {
                "Service": "appstream.amazonaws.com"
            },
            "Action": "s3:GetObject",
            "Resource": [
                "arn:aws:s3:::my-app/appdrive2.vhdx",
                "arn:aws:s3:::my-app/mount-vhd.ps1",
                "arn:aws:s3:::my-app/icon.png"
            ]
        }
    ]
}
```

When the user logs in via the web interface, they see the icon from the S3 storage. When they click on the icon there are messages about reserving the session, setting up, etc; but then after about 2-3 minutes the screen just goes black.

As suggested on another post, I set up a new Fleet with Desktop access. There is no C:\AppStream folder, no mount points and I can't see the VHD being mounted or any errors about access or anything. I opened Firefox and tried to use the S3: uri and it cannot download the VHD.

I have found various articles talking about different access settings for the S3 and VPC, but I can't understand where I'm supposed to set this up and how it relates to the issue I am experiencing.

eg, this link - I can't see how it relates to the various objects in my setup?

Hi there - since you're not seeing an AppStream folder, and aren't able to download the objects in S3 using FireFox, the issue is most likely that the streaming instance doesn't have access to S3. Does the instance have access to the Internet? Try using a subnet with a NAT gateway that has complete access to the Internet as a starting point. Then that will help isolate the issue specifically.

Hope this helps.
