Machine Learning Homework: cannot get it verified

Hello, I have been re-directed to this forum from the course mentors. I am taking the Machine Learning course the second time (I have already completed in 2013). I can take the quizzes but the system does not allow me to submit my homework for verification. I would appreciate help with this. Below is the error message that I receive after I entered my e-mail address with the token (I have tried with new token one week apart). Many thanks in advance. Best wishes, Tunde Szilagyi !! Submission failed: unexpected error: urlread: Peer certificate cannot be authenticated with given CA certificates !! Please try again later.
