assuming that the connection works properly, the only way to get stuck
in the while loop is if the size of your file is infinitely huge.

so it's probably a connection issue; I suggest adding print statements
around the conn.send and conn.close calls, to make it easier to see
where you get stuck.

setting the debug level (e.g. ftp.set_debuglevel(2)) might also provide
some additional clues.
