It was not possible to connect to the redis server(s); to create a disconnected multiplexer, disable AbortOnConnectFail. SocketFailure on PING
Solution 1
Azure Redis Cache only enables the SSL endpoint by default. The most secure approach is to set "ssl=true" when calling ConnectionMultiplexer.Connect().
Alternatively, you can use the Azure Portal to enable the non-SSL endpoint on your Azure Redis Cache, but then your password and all data will be sent in clear text.
Solution 2
I had exact same exception and it turned out to be corporate firewall, which is blocking port 6379, 6380.
I copied my test console app in an environment outside company network and connection was successful. So if Redis server is running on the internet and your network is behind a firewall make sure the ports are open.

I am trying to make a simple example of reading and writing from azure redis cache and I get this error
An exception of type 'StackExchange.Redis.RedisConnectionException' occurred in StackExchange.Redis.dll but was not handled in user code
Additional information: It was not possible to connect to the redis server(s); to create a disconnected multiplexer, disable AbortOnConnectFail. SocketFailure on PING
The code I am using is this, I changed dns and password
// Get Connection instance ConnectionMultiplexer connection = ConnectionMultiplexer .Connect("xx.redis.cache.windows.net,ssl=false,password=..."); // Get database IDatabase databaseCache = connection.GetDatabase(); // Add items databaseCache.StringSet("foo1", "1"); databaseCache.StringSet("foo2", "2"); // Add items with experation value databaseCache.StringSet("foo3", "3", TimeSpan.FromMinutes(20)); Stopwatch sw = new Stopwatch(); sw.Start(); // Get item value string foo1Value = databaseCache.StringGet("foo1"); sw.Stop(); Console.WriteLine("Elapsed={0}", sw.Elapsed); return View();
