How to create a project / Checkout password protected SVN repo using RStudio

Question

I am trying to test an existing SVN repo using RStudio. The repo is password protected, but RStudio asks for a username. I go through the process:

New Project -> Version Control -> Subversion -> Fill in all fields 

When I hit Connect after filling in all the fields, I get the following message (cleared to identify the IP address):

 svn: OPTIONS of 'https://~myIPinfo': SSL handshake failed: SSL error: A TLS warning alert has been received. (https://~myIPinfo) 

I use Chrome as my browser. Any suggestions?

EDIT: I also tried using the following forms for the username:

 1) username 2) username:password 3) domain\username 4) domain\username:password
