Getting Error 404 Not Found when deployed asp.net core web api to aws elastic beanstalk

So i built a asp.net core web api app on .NET 5.0 , it works completely fine on my machine . Today i deployed it on elastic beanstalk AWS using the aws tools .
It doesn't show any error while deploying and stuff. it just returns me code 404 not found.

Please help me 🥲

So i just made a new app without https enabling, and it just worked as i remember.

IdentityServer4 Invalid Redirect_Uri Error

I created 3 separate projects, web api project, an web mvc project, and a asp.net core app. I am using IdentityServer4 with asp.net core identity. I have a project solution id that has the information of the TestUsers. On the line RedirectUris = {"https://localhost:5444/signin-oidc"}, I am redirecting it to the project WeatherMVC. The launchsettings.json on all three files are correct and so is the RedirectUris is correct. Is there something that I am not doing correctly that is causing me to receive this message?

These two projects are under one solution which I perform a multiple startup projects.

inside of this class below Config.cs, I have the code where it will perform the Redirect_uri:

}
}
UPDATE
After adding the debugger in program.cs as suggested:
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
})
.ConfigureLogging(builder =>
{
builder.SetMinimumLevel(LogLevel.Debug);
builder.AddFilter("IdentityServer4", LogLevel.Debug);
});
I finally noticed that it is calling the redirect uri that belongs to the project named WeatherMVC using it's sslPort: 44398. Please see the launchsettings.json for that weathermvc projcect. Can't seem to understand why it is redirecting that URI if I do not have it set to that.

WeatherApi is a client to IdentityServer and when it authenticates it tells IdentityServer its redirect uri. IdentityServer checks against its allowed redirect uris and redirects if it finds a match.
This code specifies a list of VALID redirect uris not THE redirect uri.
RedirectUris = {"https://localhost:5444/signin-oidc"},
You have IISExpress and also Kestrel setup in your launchsettings.json and I think your WeatherApi project is just using the first setting that it finds as the redirect uri.
Some possible solutions are:
Add the other uri for WeatherApi to the allowed uris e.g.
RedirectUris = {
"https://localhost:5444/signin-oidc", "https://localhost:44398/signin-oidc"},
You can also change Kestrel in launchsettings.json for WeatherApi to use the same ports
"applicationUrl": "https://localhost:44398;http://localhost:65206"

I think your project is based on this tutorial. This could be helpful for people to follow the steps involved. It also has a link to the code.

if anyone have similar problem with database. Check you uri in table.ClientRedirectUris

I have faced the same error because I have missed added URLs with "http" whereas it requires "https". Confirm that you have added URLs with "https" and not the "http".
public static class RedirectUrls
{
public const string WebSigninURI = "https://localhost:44332/signin-oidc";
public const string WebSignOutURI = "https://localhost:44332/signout-callback-oidc";
}

I get an error when I use weak password on my in ASP.Net Core application

This error does not happen when I test the application in development mode on my PC, but on the remote server it does. The app verify if user exist and the password requirements, but if I use a password like "1234" the app give me this error, but it does happen if I use a password like "#juan147-lop4s785"
This is the launchSettings.json file
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:63322",
"sslPort": 44361
}

//"ASPNETCORE_ENVIRONMENT": "Development"

}
}
and this us mi Startup.cs file

//Incluye los roles de los usuarios a la app
.AddRoles<IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>();
services.AddControllersWithViews();
services.AddRazorPages();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{

}
}
}

It's likely that when creating a user, you're not checking whether it was successful or not and therefore when your "weak password" doesn't meet the default Identity options, it fails to create the user and then the database complains about the missing foreign key, resulting in your error.
Have a look here for the default Identity password options and how to customise them.
If you're using UserManager to create the user, you just need to check if it there were any errors and respond accordingly, something like the below:
var result = await UserManager.CreateAsync(user, password);
if(!result.Succeeded)
return result.Errors.Select(x => x.Description);
var roleResult = await UserManager.AddToRoleAsync(user, "User");
if (!roleResult.Succeeded)
return roleResult.Errors.Select(x => x.Description);

ASP.NET Core Webservice as localhost functional, but in IIS it gives an 404 Not Found Error

I have a problem with my ASP.NET Core Web Service.
I needed JWT for Authentication in my Angular project. That's why I made a service where the user needs to be checked, if he is authorized. I made it with .NET Core, because I have IIS Server.
When I run it locally with "dotnet run" I can make get or put requests locally. I tested it also in YARC plugin of Google Chrome by making a POST request with Payload (JSON with 2 key value pairs).
I uploaded the service in IIS Server, started it, gave the url (this time with the domain of server where IIS located) on YARC plugin in my local maschine again for POST request with the same payload. It gives me 404-Not Found Error.
Functional local url is: http://localhost:5000/api/auth/login
URL for IIS: http://myIISMachine:7471/api/auth/login (Port number is in the launchSettings.json file as well)
ConfigureServices function in my Startup.cs file:
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "http://localhost:5000",
ValidAudience = "http://localhost:5000",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("MySecretKey"))
};
});
services.AddCors(options =>
{
options.AddPolicy("EnableCORS", builder =>
{
builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod().AllowCredentials().Build();
});
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
And Configure function:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
app.UseCors("EnableCORS");
app.UseAuthentication();
//app.UseHttpsRedirection();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "api/{controller=Home}/{action=Index}/{id?}");
});
}
launchSettings.json file:
{
"$schema": "http://json.schemastore.org/launchsettings.json",
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:7471",

What am I doing here wrong? Or maybe is this something to do with the settings in IIS server? Could you help me please?

I'm not sure what is going on but I suspect that is a https problem. There is no error in the code and after debugging the code there is no error.
I'm stuck someone can help please.
Thanks in advance.
