Unable to connect AWS Redis cache in .net C# - RedisConnectionException: 'No connection is active/available to service this operation

Question

I have created AWS ElasticCache - redisCache in console. I want to access same from .net core/framework application - But unable to connect same.

        ConfigurationOptions option = new ConfigurationOptions
        {
           AbortOnConnectFail = false,
           Ssl = true,
           ConnectTimeout =5000,
           KeepAlive = 2,
           EndPoints = { "xxxxxxxxxx.cache.amazonaws.com:6379" }
        };

        ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(option);
        IDatabase db = redis.GetDatabase();
        string value = "abcdefg";
        db.StringSet("mykey", value);
        string getValue = db.StringGet("mykey");
        return getValue;

Gettitng below error -

In my case the issue was related with the DNS. (I am using a VPN to access Redis). So what I did was put the google DNS in my wifi connection and that did the trick:
