[galaxy-user] 'Could not connect to server'

I successfully uploaded files to the main Galaxy server a month ago using ftp. However, any attempts to upload files today have failed. I get a 'Could not connect to server' error when trying to connect to main.g2.bx.psu.edu<http://main.g2.bx.psu.edu> uisng FileZilla. Any suggestions? Thank you.
