关于8266Espressif的FOAT失败的问题

[zhang1531965031]

你好：
我根据官方的《ESP8266云端升级指南》这份文档，我使用了NONOS-SDK2.2与乐鑫官方的8266模块进行了调试，整个过程中都按照文档上的步骤来做的，能连接上了云服务，但是无法进行升级，在云服务器进行升级请求命令后出现了如下提示：

我已经将所需的user1与user2上传到了Espressif云服务器上，iot模块发送的ping的命令也能正常回复，但是就是不能进行升级，换了不同版本的SDK，也换了不同的浏览器，还是一样的结果，到底这是怎么回事啊？？
谢谢！！

看提示 404 Not Found，比较可能是 url 不对。

谢谢你了，我的url是乐鑫官方的url，我完全没有改动过，我把它粘贴如下：

你看这里有什么问题吗？
