Can't Log Into Developer Edition from within a Trailhead Module to complete the challenge. it keeps telling me my password is incorrect. however, i can log into my sandbox via the production link.
login to same box in seperate window and come back to main window and try again.. it worked for me. i have faced this issue for newly created developer org.
I get the same thing....cant anyone help?? i can log into the sandbox using a different browser and different tab. but not from the popup window?
Its stopping me from doing the exercises?
