I have read multiple solutions but somehow none worked for me. I am still getting CORS error. I am using a react front end and tried all solutions related to the frontend. I think my problem has to do with the backend .NET
this is how my controller CORS settings look like. I tried the wild card but it does not work either, I am now trying with the frontend address and port and still having CORS issues. any suggestion ?
[EnableCors(origins: ALLOWED_CORS_ORIGINS, headers: "*", methods: "*", SupportsCredentials = true)]
public class TroubleshootingDataController : ApiController
{
private static readonly ILog logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
private const string ALLOWED_CORS_ORIGINS = "http://localhost:3000/";
startUp.cs
[assembly: OwinStartup(typeof(WebAPI.Startup))]
namespace WebAPI
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
if (!Debugger.IsAttached)
{
//ConfigureAuth(app);
GlobalConfiguration.Configuration.UseSqlServerStorage("HangfireConnection", new SqlServerStorageOptions { SchemaName = "HangfireConnLiving" });
var filter = new BasicAuthAuthorizationFilter(
new BasicAuthAuthorizationFilterOptions
{
RequireSsl = true,
LoginCaseSensitive = true,
Users = new[]
{
new BasicAuthAuthorizationUser
{
Login = "",
PasswordClear = ""
}
}
});
app.UseHangfireDashboard("/hangfire", new DashboardOptions
{
Authorization = new[]
{
filter
}
});
app.UseHangfireServer();
}
}
}
}

On the backend on the Startup.cs just add this
On configure.
public void Configure(IApplicationBuilder appBuilder, IWebHostEnvironment webHostEnvironment)
{
appBuilder.UseCors(); // this line must before the appBuilder.UseEndPoints();
}
On ConfigureServices, we configure the cors
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddDefaultPolicy(builder =>
{
builder.AllowAnyOrigin();
builder.AllowAnyHeader();
builder.AllowAnyMethod();
});
});
}
Edit:
It seams you are using a diferent framework or something like that, that I'm used to work with.
try to add this
app.UseCors(CorsOptions.AllowAll);
before the if (!Debugger.IsAttached)
