version 4.4.2 doesn't work with Google provided token server

[wt]

The 4.4.2 doesn't work with the token server in my credential config from google (namely "https://oauth2.googleapis.com/token"). The main branch version does. Might be worthwhile to either backport that fix to 4.4.2 or document it somewhere where someone might find it.

What error are you seeing? There shouldn't be any recent changes that impact whether the examples work.
