Gandalf Docker container outbound networking appears broken

Gandalf is currently unable to make outbound HTTPSHTTPS HTTPS is an acronym for 
Hyper Text Transfer Protocol Secure. HTTPS is the secure version of HTTP, the protocol
over which data is sent between your browser and the website that you are connected
to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications
between your browser and the website are encrypted. This is especially helpful for
protecting sensitive data like banking information. requests from its Docker containers,
including WP.org ZIP downloads.

I debugged this from the app side. The consistent pattern is:
 – DNSDNS DNS is an
acronym for Domain Name System - how you assign a human readable address to a website’s
exact numeric coded location (ie. wordpress.org uses the actual IP address 198.143.164.252).
resolves successfully inside containers. – Direct TCP/TLS connections from Docker
bridge containers to external port 443 time out. – The same external probes succeed
from a temporary debug service using Docker `network_mode: host`. – This affects
WP.org, npm, Packagist, OpenRouter, and WordPress.comWordPress.com An online implementation
of WordPress code that lets you immediately access a new WordPress environment to
publish your content. WordPress.com is a private company owned by Automattic that
hosts the largest multisite in the world. This is arguably the best place to start
blogging if you have never touched WordPress before. [https://wordpress.com/](https://wordpress.com/)
endpoints, so it does not look WP.org-specific.

Could you please check Docker bridge outbound networking on the Gandalf host, and
restart Docker or the Gandalf Compose stack if that looks appropriate?

Thanks.
