Wrong Task check by System

I was Working on DAY-6 of 100Days of Cloud (AWS) where i was asked to create an EC2 Instance. I created that in provided aws account but when i checked it failed my task. It was 4th consecutive task. After 5th task i was expecting my reward of 5 tasks without redo. When i am uploading screenshot it is throwing me error.

What can i do for it now…?

This is a fairly straightforward task. What error did you get when you submitted the task?
