Could not read source map for localhost source with Unexpected 503 response from source map at local 127.0.0.1 IP address

See original GitHub issue

Describe the bug When using Ionic 5, Angular 13 and and JS Debug extension, I’m getting many errors like the following when attempting to debug the app:

Could not read source map for http://localhost:8100/styles.js: Unexpected 503 response from http://127.0.0.1:8100/styles.js.map: connect ECONNREFUSED 127.0.0.1:8100

What’s interesting is that loading up the source map address with localhost http://localhost:8100/styles.js.map instead of the IP address version http://127.0.0.1:8100/styles.js.map retrieves the file and doesn’t have a 503 response.

VS Code Version: 1.69.2 on MacOS Monterey on Silicon M1

localhost is not always the same as 127.0.0.1 when on ipv6-enabled networks

It took me weeks to end up on this solution. I think it is very important to get this fixed for a clean installed Mac Os with the latest Angular Cli. ng new and vs code debug should be working out of the box
