Microsoft R Open: Fail to install from Github, Error in utils::download.file

I'm trying to use MRAN as alternative to CRAN, reason is I want to take advantage of Intel MKL.

However I can't seem to install any libraries from Github.

For example

devtools::install_github("hadley/tidyverse")
Downloading GitHub repo hadley/tidyverse@master
Error in utils::download.file(url, path, method = download_method(), quiet = quiet,  : 
  cannot open URL 'https://api.github.com/repos/hadley/tidyverse/tarball/master'
