use https on asp.net application running on localhost

Question

I've created an asp.net web application with a web form called "Main.aspx" in it. I'm trying to run the application over https. Since I have no experiences with SSL, IIS etc. I googled how to achieve this but every solution didn't work for me.

I enabled SSL using the following steps: Enable SSL

My application is now running on https://localhost:59917/.

But if I start my application I get a Firefox error message: "Secure connection failed". So I followed the steps from Scott Gu's Blog Post but it didn't work neither.

Does anyone have experiences in SSL and ASP.net web applications and can help me out?

@CamiloTerevinto Since it has something to do with a C# asp.net web application it affects programming. — Therk

No, you are not asking how to configure ASP.NET through c#, you are asking how to configure your development server — Camilo Terevinto

If you followed the instructions, you should have configured your website on the port 443.

You should configure the binding on port 59917

If I try https: //localhost:443/Main.aspx it ends in a 404 not found error message.

Did you do the binding part of Scott Gu's Blog Post ? Can you please provide the configuration of your local IIS ?

Yes I added the binding. But with your answer you pointed me in the right direction. I added the binding on port 443 as you said. I now added a binding on port 59917 and it works now! Thx
