Better that you share your SAS code that does not work, and COPY/PASTE the exact SAS-generated log that reveals all code and associated SAS diagnostic messages. It's likely that you may not have authority/permission to access the file on the remote-host, unless you can demonstrate outside of SAS the same capability, such as with a native FTP client.
Best bet to share the code and log for effective assistance / guidance from forum subscribers.
