 $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
 ftp_pasv($conn_id, true);
 $upload = ftp_put($conn_id, "serverfile.txt", $file, FTP_BINARY);

I think you might be experiencing Bug #55651: Option to force PHP to ignore the PASV address returned. There's an issue when an FTP server behind a NAT device returns its local address in response to the PASV command. There's been a patch submitted for this issue years ago, but it hasn't made it into the source yet.

If your FTP server is behind a NAT device, try another FTP client for PHP and see if the issue persists.
