This worked for me:
$ yum list xpra | grep "^xpra"
xpra.x86_64                      0.17.0-1.el7_2
$ cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
$ xpra start :10 --start=xterm
$ xpra attach ssh:localhost:10
Attached to ssh:localhost:10 (press Control-C to detach)

Does it work if you run it locally like I did? Does "xpra list" work?

I think I may know what is happening in your case: are you launching via
su from a non-login session?
This would manifest itself as a server start up failure instead of a
client connection failure, but it would fit the bill.
More details on the awful mess created by the XDG_RUNTIME_DIR idea can
be found here:

If that's the case, you may need to create the directory
"/run/user/$UID" on the server if it does not exist yet, or edit the
config file to not refer to it.
