I see you ordered a Personal Plan, which is optimized for backing up, storing and sharing personal photo and video files. Personal plans offer more storage space at lower prices than business plans. However, personal plans can only be used for personal purposes and they don't include many business features. FTP/SFTP/Email/Web hosting features are business features. You can try these features with a personal plan. If your usage is extremely low, it might work for a long time. Otherwise, it will be blocked after a few days. You have reached your FTP/SFTP usage limit. Please upgrade to a business plan. The lowest business plan is "Business Basic with 3 users". For long time customers, please contact DriveHQ sales. We often can offer some discount, esp. if your usage is low,
