What do I do if "AccessDenied:You are forbidden to list buckets" is reported when I use an AcessKey pair to log on to OSS from ossbrowser?

Cause: Your account has no permissions to access all buckets.

  • If your account has no permissions to access all buckets, log on after you are authorized.
  • If your account is authorized to access only part of objects or buckets, log on with the AccessKey pair of an authorized account. Set Preset OSS Paths and Region.

How do I accelerate uploads and downloads when I need to upload or download a large number of objects?

Cause: By default, ossbrowser can support three concurrent upload or download tasks. Remaining tasks wait in the queue until the previous tasks are complete. When you need to upload or download a large number of objects, the default setting affects the transfer speed.

Solution: On the homepage of ossbrowser, click Settings in the top navigation bar. In the Settings dialog box that appears, modify Transfer Settings.
