使用charles对ios抓包有接口提示Charles failed to connect to the remote host

问题遇到的现象和发生背景

使用charles对ios抓包有接口提示这个错误,不知道咋解决
Charles failed to connect to the remote host. Check that your Internet connection is ok and that the remote host is accessible. Maybe your network uses a proxy server to access the Internet? You can configure Charles to use an external proxy server in the External Proxy Settings
