无法通过StackExchange.Redis重新连接到Azure Redis

警告：好的，这很奇怪，我不确定SO是否合适。

我有一个Azure网站连接到Azure Redis缓存实例。（使用StackExchange.Redis）

一切都很好，然后有一天-该网站无法连接到Redis。

错误：

无法连接到Redis服务器。要创建断开的多路复用器，请禁用AbortOnConnectFail。PING上的SocketFailure

这是我的连接字符串：

mycache.redis.cache.windows.net，ssl = true，密码= xxxxxx，syncTimeout = 5000

这是我的诊断步骤：

尝试从本地连接到Azure Redis。结果：成功（代码好吗？）

尝试启动新的Azure Redis实例，从Azure连接。结果：失败（网站无法连接到任何Azure Redis实例？）

启动具有错误代码相同代码的新Azure网站，指向现有的Redis缓存。结果：成功（嗯，什么？）

归档新的MVC网站，添加StackExchange.Redis，部署到新的Azure网站，连接到Redis。结果：成功（所以Redis好吗？）

在香草MVC网站上方部署到 现有的 Azure网站（与4相同的代码，连接到相同的Redis，唯一的区别是它使用的是旧的Azure网站物理计算机/网络）。结果：FAIL（wtf ??）

所以-我认为Redis已将Azure网站“列入黑名单”？（甚至有可能吗？）我知道 客户端

（我的代码）不会尝试保持重新连接，但是我已经多次跳出该站点，并且它无法重新连接到Redis。

通过使用 相同的代码 连接到 相同的Redis实例 来分解新的 Azure网站成功的事实告诉我，Azure /

Redis中出现了某种黑名单/路由问题。

有任何想法吗？

编辑

看起来问题出在Azure VNET。当我的网站是Azure虚拟网络的一部分时，它无法连接到Redis。但是，当我将其从网络中取出

时，它可以正常连接。在今天之前，此设置运行良好。

因此，我想知道Azure是否进行了更改，以使VNET中的网站无法连接到Azure Redis？（我不知道）
