Student pictures files not showing

[ShannonJackson1]

Hello

I created an assignment where the students had to upload a screen shot. The students can upload the screen shots but when I go to grade them it says" 502 Bad Gateway" and " Service is currently unavailable. Try again later." It was working 2 days ago and now its not. Please Help!
