Unable to connect to container running under Rancher Desktop when using Aspire 9

Is there an existing issue for this?

[x] I have searched the existing issues

Describe the bug

With the exact the same AppHost code, the connection to container cannot be made in .NET 9, but runs normal in .NET 8.

main code:

var builder = DistributedApplication.CreateBuilder(args);
var container = builder.AddContainer("web", "nginx", "1.27.2")
    .WithEndpoint(targetPort: 80);

builder.Build().Run();

Expected Behavior

Container resource running under Rancher Desktop can be reached from the host.

Steps To Reproduce
