你点击那个manifest文件能下载么？
可以能下载的
你的网址是多少 ？是内网还是外网呢
手机是连的局域网 用android studio 在手机上运行的 也是这样 用cocos的模拟器 就可以下载到指定的文件夹
要配置监听局域网的IP，你试下用手机可以打开那个内网网址不先。
cocos的模拟器可以下载的话，那估计是因为你的网址在手机上访问不到，你试试用手机打开
你这个好像是新版本了，我估计是你没有把工程里的manifestfile拖到HotUpdate脚本上。
PC模拟器能跑不？
cocos的模拟器 能下载，我用的版本是1.4 下载的21点的热更新例子 这个manifestfile怎么拖到HotUpdate脚本上
如果模拟器能下载，那就不是这个问题了。
唉~没有人知道这个怎么解决吗
你把你实现的的步骤清楚一点吧。你就问一句为啥不能下载。我们也只能回答这几点了
就是按照http://www.cocos.com/docs/creator/advanced-topics/hot-update.html这个教程一步步做的
github上的21点的热更新范例（最新版本，我测试的时候是没有问题的）是没有问题的，出问题的话 可能应该也许 是你哪里没有配置好，或者你用浏览器运行，看看控制台有无报错信息
自己检查去吧，我按这个做了没有问题，这个肯定是你自己出错了。
不能在真机上下载这个是用android studio运行的错误日志

服务器配置到外网就没问题了，在内网服务器内不知道为什么把我的服务器主机名字修改成“bogon”了
我跟你相同的问题，用的1.4的creator，你解决了吗？既然手机打开网页可以连接到服务器并下载文件，为什么游戏就下载不下来文件？和服务器主机名字有什么关系吗？
