Getting ERR_CONNECTION_REFUSED when running .NET API on localhost from Visual Studio

I’m a newbie in .NET coding, I’m trying to run a project using .NET using IIS Express on Google chrome, I get this error : ERR_CONNECTION_REFUSED

enter image description here

Here is what I’ve tried so far, and it does not work:

  • Changing the port number under properties section, and creating a new virtual directory enter image description here

  • Removing the applicationhost.config from the .vs project folder

  • Disabling the proxy

  • Running Visual Studio as an Administrator

  • Disabling the Script Debugging

Please try to visit your HTTPS address, some websites may disable HTTP connection, such as Asp.Net Core Application.

Besides, try to repair the IIS Express in the console panel.

In my case, this issue was resolved by removing the .vs file followed by restarting Visual Studio as an Administrator
