在访问存储账户的容器时，用本地电脑出现这个报错。但是换另一台电脑，却没有这个问题。

关闭防火墙、CORS权限是全部时，都无法解决，请求帮助解答

Translating the question to English:

This error occurs when accessing a container under a storage account on the local computer. However, the problem does not occur on another computer.

Disabling the firewall and setting CORS permissions to full does not resolve the issue. Please help.

English translation of the screenshot:

Hello @wanjiacheng,

Thanks for reaching out to Microsoft Q&A.

Please check for any network restrictions that could be causing the issue and also review your local network settings to see if they’re blocking the required connections.

Run the below command on both the working and non-working machines to check DNS resolution:

nslookup .blob.core.windows.net

Kindly check if the storage account is set to allow access from your local network. You might also want to check if it’s set to "Public network access" or restricted to specific virtual networks.

Make sure the user account you’re accessing from your local machine has the necessary Azure RBAC roles assigned and also role assignments include the Storage Blob Data Contributor role.

Kindly let us know if the above helps or you need further assistance on this issue.
