Chapter 11 code quiz fails due to api-inference.huggingface.co DNS resolution error

A user taking the Hugging Face LLM Course reports that the Chapter 11 code quiz fails due to a DNS resolution error for api-inference.huggingface.co, preventing submission of solutions. The issue persists despite troubleshooting attempts, and the user requests investigation into the course infrastructure or API endpoint.

Hi Hugging Face team, I’m currently taking the Hugging Face LLM Course Chapter 11 and I’m unable to complete the code quiz. Every time I submit my solution, it fails with the following error: MaxRetryError: HTTPSConnectionPool host=‘ api-inference.huggingface.co http://api-inference.huggingface.co ’, port=443 : Failed to resolve ‘ api-inference.huggingface.co http://api-inference.huggingface.co ’ The website itself loads correctly, but the code checker cannot reach the inference API, so my solutions are marked as incorrect. I have already tried: The issue still persists. Could you please check if this is a problem with the course infrastructure or the API endpoint? Hugging Face username: abhijeet0408 Thank you.
