Unable to POST to localhost:8080 using Guzzle

[blu-regard]

Description

I'm trying to get Drupal 10 to send a POST request to a local ExpressJS app that I have running on the same computer. I can hit both apps just fine using Postman but when I try to get Drupal to interact with the ExpressJS app running on localhost:8080 I get a connection refused. I get this same error when I remote into the Docksal container.

Steps to reproduce the issue:

1. Use HTTP client to send a POST request to an app running on you local computer that is not running on Drupal
2. Receive an error.
3. I've tried to run fin exec curl -I http://localhost:8080 but get the same error

Describe the results you received:

cURL error 7: Failed to connect to localhost port 8080: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://localhost:8080/my/api

Describe the results you expected:
A status code 200, currently getting a 0.

If the app is running on your host machine (Mac), then it's not "local" relative to the apps running in Docker.

The IP of the Docker VM (Linux) is 192.168.64.100 and the IP of the host (Mac) is 192.168.64.1.

To access an app running on port 8080 on the host from a container, try fin exec curl -I http://192.168.64.1:8080.
