Answer 1

I had a similar issue using R's download.file in a for loop in RStudio. It would download the url for the first several links and then I'd get "InternetOpenUrl failed: 'The operation timed out'" for all subsequent downloads. I tried the the suggestion by sssheridan to unselect the Internet Explorer option in R global options which did not work. I also tried setInternet2(use=T) but this is no longer available in R.

What worked for me was to remove the cache by including cacheOK = F as an argument in download.file. I think this is because I had previously hit the links that were timing out.
