StackExchange.Redis.RedisConnectionException

I'm trying to use Redis as a cache for blacklisting JWTs, to implement logout with JWT. I have downloaded redis on my windows 10 machine and run "redis-server.exe" and it says :

   [6112] 28 Nov 16:28:51.791 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

     Redis 3.0.504 (00000000/0) 64 bit
    
        Running in standalone mode
    
     The server is now ready to accept connections on port 6379

 

which indicates that it is working correctly.

I'm using .NetCore 3.1 , and I have Microsoft.Extensions.Caching.Redis v2.2.0 Nuget package installed.

in my startup.cs I added

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

and in my appsettings.json I have

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

but at any request I'm sending I'm getting the following exception :

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.GetAsync(String key, CancellationToken token)
   at Microsoft.Extensions.Caching.Distributed.DistributedCacheExtensions.GetStringAsync(IDistributedCache cache, String key, CancellationToken token)
   

what I'm I doing wrong? why am I getting this exception?? btw I was following this tutorial on cancelling JWTs
