This topic provides answers to frequently asked questions about ossbrowser.

What do I do if the "AccessDenied:You are forbidden to list buckets" error appears when I use an AccessKey pair to log on to OSS from ossbrowser?

Cause: You do not have permissions to access all buckets.

Solution:
  • Grant your Alibaba Cloud account the permissions and then log on to ossbrowser.
  • If your Alibaba Cloud account is not authorized to access all of the objects or buckets, log on to ossbrowser by using the AccessKey pair of an Alibaba Cloud account that has permissions to access all objects or buckets. Set Preset OSS Paths and Region.

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

Cause: By default, ossbrowser performs three upload or download tasks at the same time while the remaining tasks wait in the queue. Adjusting the number of concurrent uploads and downloads in the default setting will affect the transfer speed.

Solution: On the homepage of ossbrowser, click Settings in the top navigation bar. In the Settings dialog box, modify Transfer Settings. The number of concurrent uploads and downloads supported is determined by the hardware on which ossbrowser is installed. We recommend that you adjust and test the settings multiple times to optimize performance.

What do I do if I cannot run ossbrowser on macOS?

Cause: Applications that are not verified by developers cannot be run on macOS due to security settings.

Solution: Modify the security settings on macOS. Allow applications to run from any source.
  1. On the command line in Linux, enter a command to disable the safe mode. 
    sudo spctl --master-disable
  2. On the desktop of macOS, choose Launchpad > System Preferences > Security & Privacy > General.
  3. Click the Lock icon in the lower-left corner. In the dialog box that appears, set User Name and Password. Click Unlock.
  4. In the Allow apps downloaded from section, click Anywhere.

    After you complete these configurations, you can run ossbrowser on macOS.

What do I do if I cannot run ossbrowser after I install a software on Windows?

Cause: The software that you install adds the NODE_OPTIONS=--max-http-header-size=value environment variable to Windows.

Solution: Delete the NODE_OPTIONS=--max-http-header-size=value environment variable. The following example describes how to delete the environment variable on the 64-bit version of Windows 10:
  1. Open the Control Panel. Click System and Security. On the page that appears, Click System.
  2. In the left-side navigation pane, click Advanced system settings.
  3. On the Advanced tab of the System Properties dialog box, click Environment Variables.
  4. In the User variables list, select NODE_OPTIONS=--max-http-header-size=value, and then click Delete.
  5. Click OK.

    After you complete these configurations, you can run ossbrowser in Windows.
