Worked on the openclaw/openclaw repository to enhance the reliability of Telegram media fetches by introducing an IPv4 fallback mechanism. When initial connections failed, the system was updated to retry fetches using an IPv4-first dispatcher, addressing issues commonly encountered on networks with problematic IPv6 configurations. This approach improved error handling and reduced timeouts or unreachability errors during media retrieval. The solution was implemented in a single, well-documented commit to ensure traceability and maintainability. Leveraging skills in network programming, Node.js, and testing, the work focused on strengthening fetch resilience and robustness without introducing unnecessary complexity or altering existing workflows.
