svn co \"https://example.com/svn\"
svn: OPTIONS of \'https://example.com/svn\': SSL handshake failed: SSL error code -1/1/336032856 (https://example.com)
This question is answered in the Subversion FAQ. See *"When performing Subversion operations over SSL, I get the error SSL handshake failed...":
This can happen when the hostname reported by the server does not the match hostname given in the SSL certificate. Make sure your server configuration uses correct values for ServerName and NameVirtualHost.
A client-side fix is to update OpenSSL to version 1.0.0d.
