[Question]: WebSearch Assistant's web crawling feature returns blank

Describe your problem

I use the default WebSearch Assistant, I'm based on v0.16.0, but the result of the web page lookup is empty, how to use it? I can surf the Internet normally anywhere else

I ask a question in my local database and I get relevant results. It looks like a problem with the crawler component? I'm using the default settings.

Sorry, it's a local network issue, not a ragflow issue
