Unable to open the Odus challenge prize box. Twice.

Hi, I’m in the Odus challenge for the second time. For the last one, i saw Odus telling me I’ve completed ten quests, A box appeared on the left side of the game screen, and when I click it, there’s a message saying the connection ended in error, and i should return to the homepage to click again. And now that I possibly completed ten quests for the second time, the box is adorned with a number 2. But if I click it, the same message appears. Could you tell me what’s wrong? Ah, and I have not been able to log in to my account, nor sign up because of connection errors. How that is possible? Please help me.
