http error 400 bad request when trying to get a token

[stedogin]

i've been trying to use instaR, but failed at getting an access token - getting the response:

Authentication complete. Error in init_oauth2.0(self$endpoint, self$app, scope = self$params$scope, : Bad Request (HTTP 400). Failed to get an access token.

when examining the request using with_verbose(), i don't see any additional info. httr::with_verbose(my_oauth <- instaOAuth(app_id=client_id, app_secret=client_secret))

i saw people reporting similar issues with R FB libraries, some of them reported that reverting to an older httr version resolved the issue (due to the current version possibly having some issues with http instead of https requests).

@chcariou Could you share your sessionInfo() ? I haven't been able to replicate this error, so it's hard for me to understand what could be happening!
