550 Can't check for file existence

I can't seem to get my application to ftp from server to server. I can download from one server and upload to another. When I try a direct ftp I get the error: 550 Can't check for file existence When I read the knowledge base it says I can ignore this. I've been in the settings and set every ignore I can find.
--Exerpt from knowledge base: (The SIZE command is sent by the FTP client for two reasons. The first reason is to check for the file existence on the remote server and the second is to get the size of the remote file. If the server returns an error and the file does not exist on the server, the error can be ignored.)

When I try to transfer server to server via the global Queue ( I used the tutorial) it doesn't work either. Here is the log:

Your FTP server (ftp05.powweb.com) doesn't allow FXP (Server to Server) Transfers. FXP is usually disabled on FTP servers of hosting companies due to security reasons.

The following error is the one returned by your server. It tells you that it doesn't open a connection to a foreign IP address (the IP address of the server you want to FXP to).
500 I won't open a connection to 72.22.69.107 (only to 69.234.118.175)

Make sure both sites you are FXP'ng to/from are in the favorites. Then try to enable the "Alternative FXP" in the favorite item properties (Transfer -> FXP) of one of them. This may solve the problem if the other FTP server allows FXP (Data connections from foreign addresses).

Furtherinformation about the topic (FXP) can be found in the KB:
