Unable to call http://localhost Azure Function from https://localhost node app

Question

I have one Node.js Azure function running on a Windows 11 system at http://localhost:7071/api/FunctionName.

I can execute the function by calling it from a browser window no problem.

Now when I call it from another node app running on localhost with axios or fetch, I get an ECONNREFUSED error.

I get the same results whether I'm running from NPM start or inside VS Code. It works fine on one system.

Any suggestions? - this used to work no problem.

Thanks.

Answer 1

I just figured out a fix - calling the localhost IP address directly works: http://127.0.0.1/api/FunctionName.

Now I need to figure out what caused the configuration change.
