multiple --url on command line fails to connect.
I believe it used to work to have multiple pool url's on the command line.  If I only have 1 --url on the command line it connects fine. With more than one, it will enumerate them, but not connect, giving this error:

I'm compiled on centos 7.  Any ideas?  Did someone fix fallover and break something else?
