for most of courses getting error “An error occurred while trying to enroll this course”. Any idea how to overcome this issue?
Refreshing the page worked. 
It might take more number of refreshes,
but if the problem still persists, leave the udemy (chrome)tab for a while and then return to check.
(Checked udemy, problem only showing for discounted courses not free ones.)
