Asp.net mvc 5 应用程序 web 配置文件是

   sessionState mode="Custom" customProvider="RedisSessionProvider">
      providers>
add name="RedisSessionProvider" type="Microsoft.Web.Redis.RedisSessionStateProvider" port="6380" host="XXX.redis.cache.windows.net" accessKey="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" ssl="true" />
 providers>
    sessionState>

当我运行应用程序有错误

我也有同样的情况，最终通过添加sslprotocols=tls12到连接字符串来修复它。它不应该是必要的，但显然它是，使用最近在 Azure 上创建的 Redis 缓存。可能是由于 TLS 1.0 和 1.2 的弃用

可能是3个原因：

  1. 您的连接字符串错误（无论如何看起来都不错）
  2. 尚未创建实例（通常需要很多时间才能在 azure 中创建）
  3. 您正面临防火墙（包括 Windows 防火墙）问题

您是否能够使用命令提示符连接到 redis 缓存实例？

在此处下载适用于 Windows 的 redis

然后运行

redis-cli -h XXX.redis.cache.windows.net -a XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

你可以在这里找到一个详细的演示（西班牙语，但控制台演示仍然可用。）

NinjaTip #18 - Redis 简介

出于测试目的，请确保 Redis 服务已打开端口 6379（这是您需要在 azure 上启用的非 Ssl 端口选项）

如果您无法连接到您的实例是因为上面列出的一些原因。

我之前遇到过同样的问题，我找到了一个使用另一个解决方案的解决方案： https ://github.com/alex-simonov/RedisAspNetProviders

这个对我有用

我发现只有 web config 中的以下配置对我有用： 

<sessionState mode="Custom" customProvider="MySessionStateStore">
  <providers>
    <add name="MySessionStateStore" type="Microsoft.Web.Redis.RedisSessionStateProvider" connectionString="PUTCORRECTNAMEHERE.edis.cache.windows.net:6380,password=YOURPRIMARYKEYPUTHERE,ssl=True,abortConnect=False" />
  </providers>
</sessionState>
