Hello @Joy1,

Some possible things to check:

  1. Do you still have the same problem if you close all coursera tabs and open the lab again?
  2. Would this problem gone if you login coursera and open the lab in an incognito browser?
  3. Is your computer’s time correct? (a learner reported this as a possible cause)

Thank you for sharing points. I have to check all the cases. However, the last point may be the reason. I will check and update.

Hi, I figured out what happened. My system’s time was not correct. Thank you for sharing your points.
