经测试，一个1k以上的站点的需探活列表任务存在大量探活失败的情况（成功数量大概在100-200之间），剩余的站点就算存在并且可访问，依然会显示站点不存活，无法获取到任何信息，主要包含以下三种情况：
HTTPSConnectionPool(host='gxt.sckrdcredit.cn', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', '', 'unexpected eof while reading')])")))
HTTPConnectionPool(host='127.0.0.1', port=7890): Max retries exceeded with url: http://bmerchant.esgcc.com.cn/ (Caused by ProxyError('Cannot connect to proxy.', RemoteDisconnected('Remote end closed connection without response')))
HTTPSConnectionPool(host='analytics.rmt.sc.sgcc.com.cn', port=443): Read timed out. (read timeout=10)
