Why Can’t I Connect to Kafka? | Troubleshoot Connectivity

What this post added

This post introduces a new feature thread focused on troubleshooting Kafka client connectivity. It explains the two-step connection process (bootstrap and subsequent connections), the importance of `advertised.listeners` being resolvable from the client, and provides detailed scenarios with fixes for local, cross-machine, and Dockerized environments. It also includes a Python client example and GitHub link for code.
