ASP.NET Core 8 and Angular Vite Proxy Error: connect ECONNREFUSED 127.0.0.1:40443

I'm working on an ASP.NET Core 8 and Angular project and encountering an error with the Vite proxy setup. I'm trying to proxy requests to my ASP.NET Core API, but I keep getting a connection refused error.

Here is my proxy configuration:

const PROXY_CONFIG = [
{
context: [
"/weatherforecast",
],
target: "https://127.0.0.1:40443",
secure: false
}
]


When I try to access the /weatherforecast endpoint, I get the following error in the terminal:

[vite] http proxy error: /weatherforecast
Error: connect ECONNREFUSED 127.0.0.1:40443
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16)


Things I've tried:

• Verified that my ASP.NET Core application is running and listening on port 40443.
• Ensured that the SSL certificate is correctly set up.
• Confirmed that there are no firewall or network issues blocking the port.
• Checked that the environment variables for HTTPS are set correctly.

Environment:

• ASP.NET Core 8
• Angular with Vite
• Running on Windows 11

Has anyone encountered a similar issue or have any suggestions on how to resolve this?
