This is a Singleton Redis Helpr I am using that creates a bunch of Connection issues. Is there a better way?

RedisHelper.cs

    public sealed class RedisHelper
    {
        private static RedisHelper _instance;

        private static readonly Lazy<RedisHelper> Lazy = new Lazy<RedisHelper>(() => new RedisHelper());
        private static readonly object SyncRoot = new object();
        private static string RedisSource = string.Empty;
        public static ConnectionMultiplexer RedisConnection;
        public IDatabase RedisDb;

        private RedisHelper()
        {
            var connStr = ConfigurationManager.AppSettings[TsConstants.AppSettingKeyNames.RedisCacheConnection];
            if (connStr == null) throw new ArgumentException("Redis Connection not setup.");
            
            //creating this RedisSource to track a connection in logs to see if multiple connections are being created or not
            RedisSource = ConfigurationManager.AppSettings[TsConstants.AppSettingKeyNames.RedisSource];
            RedisSource = $"{RedisSource}-{new Random().Next(int.MaxValue)}";
            if (RedisConnection == null || !RedisConnection.IsConnected)
            {
                RedisConnection = ConnectionMultiplexer.Connect(configOptions);
                Log.Logger.Information($"Source: {RedisSource} - Built a new Redis Connection");
            }

            RedisConnection.PreserveAsyncOrder = true;
            RedisDb = RedisConnection.GetDatabase();
        }

        public static RedisHelper Instance
        {
            get
            {
                if (_instance == null)
                    lock (SyncRoot)
                    {
                        return Lazy.Value;
                    }

                return _instance;
            }
        }
}
