The FTP/SFTP service is a paid service. You can find the information on both the FTP features page and the pricing page. If you have a free service or personal service account, you can try the FTP service for a few times. You had already exceeded the limit. If you still want to try it, you can create a sub-account and use the sub-account to log in. If using a sub-account, you can:
(1) Allocate some storage space to the sub-account so that the sub-user can store files in his own My Storage.
(2) By default, sub-users are not allocated with any storage space. So you need to share a folder with the sub-user. Please watch this video for detailed information about our FTP/SFTP service. https://youtu.be/iGdBX4F1e-w
