LLM Course Final Code Quiz - Name ResolutionError (api-inference.huggingface.co) prevents certification

A user named Maleeha Riaz reports a persistent DNS resolution error for api-inference.huggingface.co while attempting to complete the final coding quiz of Hugging Face's LLM course, preventing certification despite troubleshooting across multiple devices and networks over five days.

Hello, I have completed the entire Hugging Face LLM course. The only remaining requirement is the final coding quiz. Whenever I submit my solution, I receive the error “Failed to resolve api-inference.huggingface.co http://api-inference.huggingface.co ” attach snapshot . I have already tried multiple times: Chrome, Firefox, Incognito mode, different Wi-Fi networks, mobile hotspot, laptop, and mobile phone, waiting more than 5 days. The problem persists, so it appears to be a server-side issue. My Hugging Face username: Maleeha Riaz Could you please investigate? This issue is preventing me from completing the course and receiving my certificate. Thank you.
