从 Visual Studio 在本地主机上运行 .NET API 时获取 ERR_CONNECTION_REFUSED

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

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.

Answer 2

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.

Feel free to let me know if the problem still exists.

Answer 3

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