Hi all,

Trying to do regular FTP to a site we haven't connected to before.
Testing it manually before setting up an automatic process.

When I enter the user id and password I get this:
503 Invalid sequence of commands (AUTH SSL/TLS required prior to authentication).

Any idea what could cause this?

Thanks,
Charlie
