'powder-sse(2/3) proxy:{address}:{port}' where {address} is the address of the proxy and {port} is the port.
On a Mac, this is a bit more complicated, you must open a terminal and go to the directory with Powder.app in, and issue the command
'Powder.app/Contents/MacOS/powder-x proxy:{address}:{port}'.

It means that the Powder Toy cannot communicate with the server, usually because there is no internet connection, or the port used (port 80) has been intentionally blocked by an administrator.

Another known cause is Firewall or internet filtering software that runs on the computer (e.g Windows Live Family Safety), if this is the case, the relevant proxy settings need to be acquired, or the software disabled.
