[ArtOfCode-]

This is the CAPTCHA problem again. If two builds are close enough together, they'll trigger a CAPTCHA from SE and suddenly we can't log in.

If the CAPTCHA isn't something we can solve now, we can close this issue for now - it's been worked around by aborting that very test mid-way if login fails.
