設備上的Proxy代理被上次自動化運行占用未被釋放導致的
一般Node.js提供的HttpServer默認設置了超時時間為2分鍾，當一個請求的處理時間超過2分鍾，HttpServer會自動將該請求的socket關閉掉，於是客戶端便收到了 ECONNRESET 的錯誤信息了；當然這里不是因為時間的問題 是直接報超時error ，主要的原因就是HttpServer進程被上次自動化一直占用，所以會導致一運行就會報ECONNRESET 的錯誤，由於uiautomator對應的端口全被占用了，一般重啟設備或刪除Appium的所屬App即可這個報錯是由於uiautomator對應的端口全被占用了，重啟手機即可
