DotNet not valid certificate found

2

I have seen this questions many times, but none of the answers works for me. My DotNet Core app fails

The code:

    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

the error:

System.InvalidOperationException
  HResult=0x80131509
  Message=Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.
To generate a developer certificate run 'dotnet dev-certs https'. To trust the certificate (Windows and macOS only) run 'dotnet dev-certs https --trust'.
For more information on configuring HTTPS see https://go.microsoft.com/fwlink/?linkid=848054.
  Source=Microsoft.AspNetCore.Server.Kestrel.Core

This exception was originally thrown at this call stack:
[External Code]
AccionesWeb.Program.Main(string[]) in Program.cs

When I try to create a cert, it creates it without problem, but then it says not found

PS ...> dotnet dev-certs https -t
Trusting the HTTPS development certificate was requested. A confirmation prompt will be displayed if the certificate was not previously trusted. Click yes on the prompt to trust the certificate.
The HTTPS developer certificate was generated successfully.

PS ...> dotnet dev-certs https -c
No valid certificate found.

I found the solution. I had to manually delete all certs because dotnet dev-certs https --clean was not removing all of them

If you are facing this issue, delete all localhost certificates with friendly name ASP.NET Core... from:

  • Current User > Personal > Certificates
  • Current User > Trusted root certification authorities > Certificates
