IOS 应用程序无线分发 : error when download can't connect to domain
<p><p>我们目前正在 IOS 和 Android 上通过无线方式部署一个新应用程序，android 可以通过简单的链接在互联网上下载 apk，但在 IOS 上，当我们尝试从下载链接。
"无法连接到 "domain.com""</p>
<p>我不知道出了什么问题:plist 很好，ipa 也很好，我用浏览器检查了所有链接。</p>
<p>plist 和 ipa 的 MIME 类型是:
plist:文本/xml
ipa : 应用程序/八位字节流</p>
<p>https://端口自定义为8443
<a href="https://domain.com:8443/webapp/app.html" rel="noreferrer noopener nofollow">https://domain.com:8443/webapp/app.html</a> </p>
<p>下载链接:</p>
<pre><code><p><a href="itms-services://?action=download-manifest&url=https://domain.com:8443/webapp/app.plist">DownLoad Iphone APP</a></p>
</code></pre>
<p>这样的plist文件:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</array>
</dict>
</plist>
</code></pre>
<p>我的网络服务器位于运行良好的反向代理 nginx 后面(反向代理和网络服务器之间有 8443 到 8080 的转换)等。</p>
<p>当我尝试下载应用程序时，反向代理的日志显示了这一点，奇怪的是我收到了 503 错误，但是所有像 chrome 这样的浏览器都有 .ipa 的 HTTP 响应 200 OK，但是当我点击我的下载时iphone 我在 nginx 日志上收到 503 错误:</p>
