mind+2.0更新开发板资源清单失败

各位大神，怎么mind+2.0上传模式不能加载硬件主控板了，显示“更新开发板资源清单失败”正在下载 package_index.tar.bz2 索引 Get "https://downloads.Arduino.cc/packages/package_index.tar.bz2": read tcp 192.168.31.213:51802->104.18.10.21:443: wsarecv: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
初始化实例时出错：一些索引无法更新

请问怎么解决呢？急！！！
