Unable to access the challenge

Hi, I tried to access the challenge but the email sent to me when I choose “sign in by email” directs me to an empty page with a Json message: “{“message”:”"}". I’m not sure how to actually access the challenge now.

I get that message sometimes - and I have seen my colleagues get something similar too. I just rebooted and the message went away, and I was directed to the challenge dashboard.

Hum, I haven’t seen that before. Did the reboot solve the problem?
