Can not connect to Crawl4AI server

[ilredirana]

Crawl4AI version: 0.6.0rc1-r1 and above

Error message: PluginInvokeError: {"args":{},"error_type":"ToolProviderCredentialValidationError","message":"连接到Crawl4AI服务器失败：HTTPConnectionPool(host='localhost', port=11235): Max retries exceeded with url: /crawl (Caused by NewConnectionError('\u003curllib3.connection.HTTPConnection object at 0x7f84d8540e30\u003e: Failed to establish a new connection: [Errno 111] Connection refused'))"}

Description: It requires API token on the web page. But when I input a random one, it has a PluginInvokeError.
