Unable to pull docker image for pixel streaming on Linux server

I am unable to pull docker image for pixel streaming on Linux server.

[root@server~]# docker pull ghcr.io/epicgames/pixel-streaming-signalling-server:4.27.2
Error response from daemon: unauthorized

When I tried docker login it returns "Login Succeeded", but I am still unable to download the image.

[root@server~]# echo $CR_PAT | docker login ghcr.io -u <username> --password-stdin

    After 2 days of research, I found out that the GitHub personal access token did not have sufficient rights to download the image. After modifying these rights, I was able to download this image.

    For people who are still looking for details of the solution to this issue.

    If you’re trying to pull docker images from the "ghcr.io/epicgames" GitHub Container Registry, you’ll need to authenticate using a GitHub Personal Access Token (PAT).

    Here’s how to do it:

    1. Make sure your GitHub PAT has not expired. If needed, update it at https://github.com/settings/tokens.

    2. In the "Select scopes" section of your token, make sure that the "read:packages" scope is checked. You can review this screenshot.

    3. Log in to the GitHub Container Registry using your PAT:

    docker login ghcr.io --username=YOUR_GITHUB_USERNAME --password=YOUR_PERSONAL_ACCESS_TOKEN

    Once you’ve completed these steps, you should be able to pull the image from the registry.

    For more information, you can refer to the official Unreal Engine documentation on using container images.

    I hope this information helps. Happy coding!
