Hi Kruthika,

This seems to be a general issue, do you have proxy setup in your browser settings?

Hi guys, I have the same problem. But my browsers are pretty vanilla configurated. Had the same problem on a mac - safari & w/ a win7 chrome. There is a login loop that doesnt let me start the challenges :(

Any clue?

This is the login pop up that always fall back to that call to action 
recurse login pop up that never actually login
