Redis Timeout

StackExchange.Redis.RedisConnectionException: No connection is available to service this operation: GET ippp;

I use the lazy pattern:

private static ConnectionMultiplexer _instance = null;
public static ConnectionMultiplexer Instance
{
            get
            {
                return conn.Value;
            }
}

private static Lazy<ConnectionMultiplexer> conn = new Lazy<ConnectionMultiplexer>(
  () =>
  {
      _instance = ConnectionMultiplexer.Connect(“127.0.0.1:6379,password=123456,connectTimeout=5000,syncTimeout=10000,abortConnect=false”);
      _instance.ConnectionFailed += MuxerConnectionFailed;
      _instance.ConnectionRestored += MuxerConnectionRestored;
      _instance.ErrorMessage += MuxerErrorMessage;
      _instance.HashSlotMoved += MuxerHashSlotMoved;
      _instance.InternalError += MuxerInternalError;
      return _instance;
  }
  );

Could you please help as we are getting this error in production.

I think I've solved it

I am also getting this issue

If you use synchronous method calls, continue to use synchronous methods,vice versa.
for example:

public static ConnectionMultiplexer Instance
        {
            get
            {
                return conn.Value;
            }
        }

        private static Lazy<ConnectionMultiplexer> conn = new Lazy<ConnectionMultiplexer>(
        () =>
        {
            _instance = ConnectionMultiplexer.Connect("your redis conn");
            _instance.ConnectionFailed += MuxerConnectionFailed;
            _instance.ConnectionRestored += MuxerConnectionRestored;
            _instance.ErrorMessage += MuxerErrorMessage;
            _instance.HashSlotMoved += MuxerHashSlotMoved;
            _instance.InternalError += MuxerInternalError;
            return _instance;
        }
        );

        private static readonly SemaphoreSlim _connectionLock = new SemaphoreSlim(initialCount: 1, maxCount: 1);
        public async static Task<ConnectionMultiplexer> InstanceAsync()
        {
            if (_instance != null)
            {
                return _instance;
            }
            await _connectionLock.WaitAsync();
            try
            {
                if (_instance == null)
                {
                    _instance = await ConnectionMultiplexer.ConnectAsync("your redis conn");
                    _instance.ConnectionFailed += MuxerConnectionFailed;
                    _instance.ConnectionRestored += MuxerConnectionRestored;
                    _instance.ErrorMessage += MuxerErrorMessage;
                    _instance.HashSlotMoved += MuxerHashSlotMoved;
                    _instance.InternalError += MuxerInternalError;
                }
            }
            finally
            {
                _connectionLock.Release();
            }
            return _instance;
        }

        public static IDatabase GetDatabase(int dbIndex)
        {
            return Instance.GetDatabase(dbIndex);
        }

        public async static Task<IDatabase> GetDatabaseAsync(int dbIndex)
        {
            var conn = await InstanceAsync();
            return conn.GetDatabase(dbIndex);
        }

        public static string StringGet(int dbIndex, string key)
        {
            var db = GetDatabase(dbIndex);
            if (db != null)
            {
                return db.StringGet(key);
            }
            return string.Empty;
        }

        public static async Task<string> StringGetAsync(int dbIndex, string key)
        {
            var db = await GetDatabaseAsync(dbIndex);
            if (db != null)
            {
                return await db.StringGetAsync(key);
            }
            return string.Empty;
        }
