Hi, I created a private group, and then I create a domain for this group (follow by this blog of Mike https://codeforces.com/blog/entry/51787)

I added a mashup contest to the group and set "Allow view other submissions to:" with "anyone":

I can view other submissions by the link https://codeforces.com/group/GROUP_ID/contest/CONTEST_ID/submission/SUBMISSION_ID

But if I use domain link (like domain.contest.codeforces.com) to enter the group, I cannot view the submissions of other users (it say "You are not allowed to view the requested page" when I use the link: https://GROUP_DOMAIN.contest.codeforces.com/group/GROUP_ID/contest/CONTEST_ID/submission/SUBMISSION_ID).

It's fine if you have a codeforces account (just don't use the domain link), but the problem is I created some domain accounts, and they cannot view the submissions (since the group is private and they cannot enter the group unless I invite them to join the group, which is not what I want)

Is it a bug or I did something wrong?

Thanks

Hi, I created some mashup contests via polygon link about 2 weeks ago, everything is right 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: .

But after few hours, everything turned back to normal.

For more details:

• mashup id is 274862

• I added it to a public group, contest link. Right now many problems in that mashup are not accessible (proof). Btw there are many mashups in that group has the same "Can't read or parse problem description" problem.

• Polygon link: https://polygon.codeforces.com/p8gcXPh/tuvietthao/voj-vosnseq

I have done:

• Create a package

• Give access to 'codeforces' account in polygon

(proof)

But seems like it doesn't work.

Have I done something wrong? MikeMirzayanov Could you take a look?

Thanks, sorry for my poor English.
