Cannot make connection to host

Same as others. I can connect with filezilla with same parameters. I was able to connect 2 days ago with same setup. I redid the site server from scratch same results. Error box indicated I need proxy. We don't have a proxy. I've tried with firewall off, passive checked or unchecked, no diff.

Now a different user connected after me yesterday, so something could have changed but what? Filezilla still works.

FTP log has nothing/empty.  Wireshark shows connection with a Request followed with a short Response from server. Then nothing more. Filezilla has Request/Response repeated many times.
