It's not about the password, you have firewall issues.

I've seen that issue happen to a fellow developer slightly less than
two years ago.  The packet you're expecting at this point is as large
as it can be, and apparently some stateful packet filters (that
understand FTP) are confused by that packet.

In that story, it appeared that some version of the Checkpoint firewall
actually expected TCP packets to be aligned with end of lines, which was
not the case with the motd of the time, for two bytes.  That is, making
the motd file two bytes larger (I suggested increasing the length of the
fork at the time) made the connection get through.

I don't remember if admins@ did something about it at the time, and I
guess the motd has changed by now, but I really think you're experiencing
a similar issue.

It might also be related to PPPoE and badly negociated MSS.

By the way, the 421 message you get comes from the FTP client, not the
server.
