No internet access from Home Assistant Docker Container

I currently have a very strange issue where all external services have stopped working.
I have narrowed it down to my Docker not being able to access the internet (Confirmed with PING via SSH)

I have deleted and recreated the Docker with no success (when connecting to existing /config directory).

If I create a new container it works fine, but seems to not work when connecting to existing configuration.
Any suggestion on what file within my configuration (or .storage) directory that may cause such an error?

I would like to retain my existing devices and not have to set everything up again - if possible.

Details might help

Example service and ‘since when/what’ … things donot stop like that so something must have changed

Docker stack/compose/setup

Paste configuration.yaml (obfuscate any private data/id in there)
