Failed to fetch error while loading Coursera labs

Hi, Durgesh Rao.

Welcome to the community.

Here, you can find some of the solutions.
1.Did you try login in again?
2. Is your network speed fine?
3. Try opening in some other browser.
4. As per Coursera’s troubleshooting articles support: You’ll only be able to access your Coursera Lab assignments and Jupyter Notebooks if you have a paid Coursera membership. If your subscription ends, you’ll be put into audit mode and won’t be able to access them.
4. If none of the above pointers are making any of the solutions then try reaching out to Coursera.
