Hi, I created some mashup contests via polygon link about 2 weeks ago, everything is fine at that moment.
But in the past 2-3 days, especially while codeforces having a contest, my mashups seem to be failed (right now it's failed). It said "Can't read or parse problem description" when I enter a problem. At the dashboard page of the contest, I noticed this: 
. After feel hours, everything turns back to normal.
For more details: - mashup id is 274862
- I added it to a public group, contest link
I have done: - Package the problem in polygon
- Give access to 'codeforces' in polygon
(proof)
But seems like doesn't work. 
Did I do anything wrong? Thanks.
