Problem: Let's Encrypt SSL fails to work even it has been activated on the Control Panel Solution: This solution applies to ASP.NET Core application with MVC The problem is that Let's Encrypt SSL targets a folder .well-know inside the application. As it does not exist on the httpdocs, and that no route is targeting it, MVC will return a 404 error message and then SSL Certificate will not work. So the trick is to add the following code on the configure method from startup.cs
app.UseStaticFiles(new StaticFileOptions
{
FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), @".well-known")),
RequestPath = new PathString("/.well-known"),
ServeUnknownFileTypes = true // serve extensionless file
});
And you also need to add the folder to the root of the website As Let's Encrypt SSL is a new feature to the Plesk Control Panel, occasionally, it will not work fine. We still highly recommend our customer to use a paid SSL for higher reliability and security reason If there is any further issue, please open a support ticket via our Help Desk System |
