ASP.NET Webforms app error: MetadataAddress or Authority must use HTTPS unless disabled for developm

moondaddy 911 Reputation points

Using VS 2022 I just created a new Asp.Net app using the Weforms tamplate along with Identity authentication. I built the app and tried to run it but get this error in the browser:

The MetadataAddress or Authority must use HTTPS unless disabled for development by setting RequireHttpsMetadata=false.

I had no option other than using https in the template setup. You would think VS would configure this to run without error and of course I don't have a ssl certificate ready at hand to use. I googled the error but only found examples related to this in c# and I don't know where in c# to set this. I assumed it would be web.config setting but found zero examples of this in google.

any advise on how to get past this error so I can run the app?

    Hi @moondaddy ,
    I think you need to add JwtBearerOptions.RequireHttpsMetadata as false, but only disable in development environment.

     public void ConfigureServices(IServiceCollection services)  
                services.AddAuthentication(options =>  
                    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;  
                    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;  
                }).AddJwtBearer(options =>  
                    options.Authority = Configuration["Auth0:Authority"];  
                    options.Audience = Configuration["Auth0:Audience"];  
                    options.RequireHttpsMetadata = false;  

    Best regards,
