PHP: Guzzle 6 - cURL error 7 Connection Refused

The issue is that your hosts file on your local machine will not impact how the docker instances map an IP to a host.

Try accessing the endpoints via the container name...

This turned out to be a relatively simple fix. The problem was the two fpm containers weren't aware of each other, and by referring to app-one.local in app-two's request, app-two was basically sending the request into the void. The fix for this was as follows:

What I ended up doing is creating an overlay network, and making the nginx container aware of each of the fpm's domain name. This allows the two containers to now send requests back and forth between each other via FQDN as opposed to IP or container ID/name. A simple thing to overlook in hindsight.

In My case URL was not valid i was missing the "https://" in start of URL. when add it was fine
