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

Question

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

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

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

• Disabling the proxy

• Running Visual Studio as an Administrator

• Disabling the Script Debugging

Answer 1

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

Answer 2

While creating the database connection try to use port number with localhost it worked for me so might go same with you as well.... Good luck.
