What's Wrong?

The Claude in Chrome extension blocks all interactions with d4bfunemain.wsgjp.com.cn (网上管家婆 ERP system), showing "This site is blocked by your organization's policy."

This is a legitimate B2B ERP/inventory management system (管家婆网店ERP) widely used by Chinese SME retailers to manage inventory, orders, and sales data.

Error message received:

This site is blocked by your organization's policy.

Affected tools: find, read_page, navigate — all return the same block error.

URL: https://d4bfunemain.wsgjp.com.cn/Main.gspx

Use case: Using Cowork desktop mode to automate inventory queries and reporting on the ERP system.

What Should Happen?

Claude in Chrome should be able to read and interact with this ERP page normally — find elements, read page content, and navigate within the site — just like any other legitimate business web application.

Additional Information

This issue affects Claude Cowork mode users who use business ERP systems. The domain wsgjp.com.cn is the official server for 管家婆网店ERP (Guanjiapo), a leading ERP platform used by tens of thousands of Chinese e-commerce businesses.
