Please try submitting again in 10 minutes. If the problem persists for 24 hours, please reach out to Coursera through our Help Center.

I am trying to refresh workspaces but not fix the problem.

Please could the mentor check my problem?

Thank you very much!

This is an issue from an earlier discussion thread that is probably being fixed. you can wait for sometime.

Hi @dntai,
Is this problem fixed? Please let me know.

Thank you!

Thank you very much! I already fixed this problem.

I am still experiencing the problem. It has been few days now. This “Platform Error…” page does not lead to access to the iPython Jupyter Notebook, so I cannot resubmit the assignment either.
