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

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” (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.
