Suddenly cannot upload files on server from computers using proxy for net

HI ,
suddenly i cannot upload files on server ftp.example.com from our network computers(we use proxy software to share net). Though i can upload from main computer directly connected to net. I was able to upload files from our network computer before a day !!
I am using ccproxy and cute ftp . My server is with go daddy .
this seems to be a network problem or ISP problem…i tried from another computer in network but could not upload files…

It’s most likely a change in proxy filters/setting either at their end or yours. You might need to ask your Network Administrators if they have blocked or changed any FTP access/privileges.
