我尝试使用redis作为jwt黑名单的缓存，用jwt实现注销。我已经下载了redis在我的windows10机器上运行 "redis-server.exe" 上面写着：

[6112] 28 Nov 16:28:51.798 # Server started, Redis version 3.0.504
[6112] 28 Nov 16:28:51.799 * DB loaded from disk: 0.001 seconds
[6112] 28 Nov 16:28:51.800 * The server is now ready to accept connections on port 6379

     Redis 3.0.504 (00000000/0) 64 bit

        Running in standalone mode

     The server is now ready to accept connections on port 6379

这表明它工作正常。
我用的是.netcore 3.1 Microsoft.Extensions.Caching.Redis 已安装v2.2.0 nuget包。
在我的 startup.cs 我补充道

services.AddDistributedRedisCache(r =>
            {
                r.Configuration = Configuration["Redis:ConnectionString"];
            });

在我的心里 appsettings.json 我有

"Redis": {
    "ConnectionString": "localhsot"
  }

但在我发出的任何请求中，我都会得到以下例外：

StackExchange.Redis.RedisConnectionException: It was not possible to connect to the redis server(s); to create a disconnected multiplexer, disable AbortOnConnectFail. SocketFailure on PING
   at StackExchange.Redis.ConnectionMultiplexer.ConnectAsync(String configuration, TextWriter log) in c:\code\StackExchange.Redis\StackExchange.Redis\StackExchange\Redis\ConnectionMultiplexer.cs:line 801
   at Microsoft.Extensions.Caching.Redis.RedisCache.ConnectAsync(CancellationToken token)
   at Microsoft.Extensions.Caching.Redis.RedisCache.GetAndRefreshAsync(String key, Boolean getData, CancellationToken token)
   at Microsoft.Extensions.Caching.Redis.RedisCache.GetAsync(String key, CancellationToken token)
   at Microsoft.Extensions.Caching.Distributed.DistributedCacheExtensions.GetStringAsync(IDistributedCache cache, String key, CancellationToken token)

我做错什么了？为什么我会得到这个例外？？顺便说一句，我是按照这个教程取消jwts
