Sorry, I had ended up switching to http to avoid having to change the dropdown. Yes I am using the Microsoft.AspNetCore.OpenApi generator.

I now understand you get a list of urls from somewhere. Just don't understand why the gui couldn't default to choosing the 1st url that possibly matches what the gui was launched on.

@xC0dex clearing the servers using document transformer did work, thanks

.net 9 and scalar.aspnetcore 2.4.7 code

options.AddDocumentTransformer((document, _, _) =>
{
    document.Servers = [];
    return Task.CompletedTask;
});

I have the same issue, but only when running in Azure (Container Apps) and hitting the public https endpoint. I published the app using dotnet publish (to containers, docker image), but I assume the container itself is running the app on localhost:8080 (default port).

Same solution to modify Servers?

Hey @johnkors,

Yes! It's the same issue. 👍

Hi, I think you can try this to see if it becomes the base server:

app.MapScalarApiReference("/scalar/v1",
    (options, context) =>
    {
        // ...
        if (context.Request.Scheme == "https")
            options.AddServer(new ScalarServer($"https://{context.Request.Host}"));
        options.AddServer(new ScalarServer($"http://{context.Request.Host}"));
    });
