It's ok now, just try to clean cache. I think it was just ddos on their oauth server. Nothing to afraid, it's not a security issue, but they asked to change credentials just to be sure that everyone are protected.
I'm new here, have an offtopic question: I want to buy 200 TH/s and switch my life to this income. Can anyone share their income from there (I mean who there more the 1year)
tnx
