Devcontainer can't reach Visual Studio Marketplace

I have the following devcontainer configuration:

{
    "name": "[Dev] MyDevContainer",
    "dockerComposeFile": ["../docker-compose-dev.yml"],
    "runArgs": [
       "--network=host"
     ],
    "service": "orchestrator",
    "workspaceFolder": "/workdir",
    "postCreateCommand": "sudo ./build.sh",
    
    "customizations": {
        "vscode": {
            "extensions": [
                "GitHub.vscode-pull-request-github",
                "databricks.databricks",
                "github.copilot",
                "github.copilot-chat",
                "mechatroner.rainbow-csv",
                "ms-python.vscode-pylance",
                "ms-python.pylint",

                "ms-python.debugpy",
                "mhutchie.git-graph",               
                "paiqo.databricks-vscode",
                "redhat.vscode-yaml"
            ]
        }
    }
}

My docker compose is:

However, I get this error:

What should I be doing differently to resolve this issue?
