The other host is working fine if used with online ftp client(net2ftp). I have also checked the credentials but the same error persists. Also, My friend has another account on the 'Johny' server. If I try to upload files on the 'Johny' server via ftp, only 230mb of data can be transferred even if the remaining space is 450mb. Please check whether port 21 is open for outgoing connections and does it have some data limit or not. Thank You...
