So I’m for some days now trying to solve a cors error problem i’m having, however I already did a lot of tries on “Program.cs” file to try to solve this but I can’t figure this out..

Basically the cors error only happen on post methods, I’m using this on Program.cs

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddHttpClient();
builder.Services.AddCors(builder =>
{
    builder.AddPolicy("AllowAll", options =>
    {
        options.AllowAnyOrigin()
            .AllowAnyMethod()
            .AllowAnyHeader();
    });
});

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();
app.UseRouting();

app.UseCors("AllowAll");

app.UseAuthorization();

app.MapControllers();

app.Run();

On the browser console I see this:
Access to XMLHttpRequest at ‘https://localhost:7278/api/Topaz/SetTabletState’ from origin ‘https://example.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Can anyone help me figuring this out?

I already tried to put the domain on the origins but still does not work.
I already tried to define the cors policy in the controller but still does not work.
