I just solved it again, so the challenge itself does seem to be working. The issue you mention is something I've run into before as well, and is a site-wide issue. What's happening is that you changed things up mid-session, and that's what gets you automatically logged out. Try logging in with things already set as you need them to be to solve the challenge. (This goes for other similar challenges too since, as I said, it seems to be a site-wide policy rather than anything challenge specific)
