RCurl errors when fetching ssl endpoint

问题:

RCurl is giving me an error:1411809D:SSL routines:SSL_CHECK_SERVERHELLO_TLSEXT:tls invalid ecpointformat list when I try to connect via SSL to an https (not public, unfortunately) endpoint to fetch some JSON.

I've put ssl.verifypeer = FALSE, and I don't know how to adjust the cipher list to avoid ECC suites.

How do I fix this? It works fine in the browser.

The issue is described here for python. Setting sslversion=3L in your RCurl call with ssl.verifypeer=TRUE should resolve the problem.
