My company is currently using FTP to receive files from customers, but some customers always have problem accessing our FTP server e.g. connection broken midway transferring files, prompted "connection terminated" when they log in, prompted "make sure you have the permission to access...", and some cannot even get to the log in dialogue box.
Ironically, when I try to log in using their account from my house, no problem at all. So I'm wondering whether this is the problem with their internet connection? Or maybe really have problem at our end? Because they claimed that they have no problem accessing FTP of other suppliers.
Is there any better way to transfer files other than FTP?
Thanks.
