To be fair, my requests to this service are also blocked unless I use Tor Browser. This could be an aggressive case of GeoIP banning. (Blocking a well-known university but not blocking Tor exit nodes? Talk about security theatre.) Another reason could be that R CMD check uses libcurl with its default User-Agent: libcurl/A.BB.C to check URLs, and the remote server could deny requests from such automated user agents, only allowing clients that look like browsers. I have no data to confirm this hypothesis. -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
