Common issues and solutions for ossbrowser 2.0.
How to get the ossbrowser 2.0 log file
If your issue is not covered here, collect the ossbrowser 2.0 log file and contact support. Package the entire ob2 folder from one of these default paths:
| Operating system | Log path |
|---|---|
| Windows | C:\Users\your_username\AppData\Roaming\oss-browser2\ob2/ |
| macOS | /Users/your_username/Library/Application Support/oss-browser2/ob2/ |
| Linux | ~/.config/oss-browser2/ob2/ |
AccessDenied:You are forbidden to list buckets
This error appears when you log on with an AccessKey that lacks permission to list all buckets. Two ways to fix it:
Grant the missing permission. Add the
oss:ListBucketspermission to the current account, then log on again. For details, see Grant permissions to a RAM user.Scope access to specific buckets. If the account should only access certain buckets or objects, add an access path in the Preset OSS Path field and select the Region where the bucket is located. For setup instructions, see ossbrowser 2.0 (Preview).
Cannot connect due to network issues
This is almost always a proxy misconfiguration, either an incorrect proxy or one that cannot reach the internet. Check the proxy settings for your operating system:
| Operating system | Where to check |
|---|---|
| Windows | Internet Options |
| macOS | Network Preferences |
| Linux | System Settings > Network > Network Proxy |
If the proxy settings look correct, try temporarily disabling the proxy to confirm whether it is the cause.
Does downloading files cost anything?
Yes. Downloading files from OSS to your local machine through ossbrowser 2.0 incurs outbound traffic fees. For pricing details, see Traffic fees.

What does "Pulled x items" mean?
The Pulled x items indicator in the lower-left corner of the file list shows the number of file entries that ossbrowser has currently cached locally.
Starting from version 2.1.1, ossbrowser continuously calls the ListObjectsV2 operation in the background to fetch and cache the file list. This continues until either all objects in the folder are listed, or the cache contains at least (number of pages x entries per page) items.
The cache clears automatically when you refresh the page, search by prefix, or switch folders.
