Problem connecting by FTP for data upload on a private Cloud Galaxy server using Filezilla

Hello,
I am having difficulty in uploading data to the FTP server of http://phln.genome.edu.au/galaxy/. The response i am getting is :
Response: please contact:

Response: galaxy-bugs@bx.psu.edu
Response:
Response: Files uploaded via FTP and not imported to a history within three days will be
Response: deleted.
Response: 220 ProFTPD 1.3.5 Server (Galaxy CloudMan FTP) [45.113.233.101]
Command: AUTH TLS
Response: 500 AUTH not understood
Command: AUTH SSL
Response: 500 AUTH not understood
Error: Critical error: Could not connect to server

I was able to transfer to FTP server of other galaxies but i can’t for this one.

Under encryption, I am selecting ‘Require explicit FTP over TLS’. Although, its seem to be connecting if i use normal quick connect without this encryption but it’s extremely slow, which is impossible to use.

Thanks for your help
