Microsoft.WindowsAzure.Storage (Azure Storage SDK for Windows) version : 9.3.2.0 : Microsoft.WindowsAzure.Storage.StorageException: The remote server returned an error: (403) Forbidden.

Question

Hi,

I am using Microsoft.WindowsAzure.Storage (Azure Storage SDK for Windows) version : 9.3.2.0 for uploading the blob.

Here is logic of c# code for the same.

    private class FileBlock
    {
        internal string Id { get; set; }
        internal byte[] Content { get; set; }
    }

    public static async Task<Uri> UploadFileToAzureStorageAsync(string azureStorageUri, string filePath)
    {
        var bytes = File.ReadAllBytes(filePath);

        var cloudBlockBlob = new CloudBlockBlob(new Uri(azureStorageUri));

        var blocks = new HashSet<string>();            

        try
        {
            foreach (var block in GetFileBlocks(bytes))
            {
                cloudBlockBlob.PutBlock(block.Id, new MemoryStream(block.Content, true), null);
                blocks.Add(block.Id);
            }

            await cloudBlockBlob.PutBlockListAsync(blocks);
        }
        catch (Exception ex)
        {
            Logging.logger.Error(ex);                
        }

        return cloudBlockBlob.Uri;
    }

    private static IEnumerable<FileBlock> GetFileBlocks(byte[] fileContent)
    {
        if (fileContent.Length == 0)
            return new HashSet<FileBlock>();

        var maxBlockSize = 4 * 1024 * 1024;
        var hashSet = new HashSet<FileBlock>();
        var blockId = 0;
        var index = 0;
        var currentBlockSize = maxBlockSize;

        while (currentBlockSize == maxBlockSize)
        {
            if ((index + currentBlockSize) > fileContent.Length)
                currentBlockSize = fileContent.Length - index;

            var chunk = new byte[currentBlockSize];

            Array.Copy(fileContent, index, chunk, 0, currentBlockSize);

            hashSet.Add(new FileBlock
            {
                Content = chunk,
                Id = Convert.ToBase64String(BitConverter.GetBytes(blockId))
            });

            index += currentBlockSize;
            blockId++;
        }

        return hashSet;
    }

I am seeing this issue intermittently for few packages. If i publish again it will be successful. I read few blogs which suggest to change machine to UTC time zone. I tried that as well but still the same error occurs as shown below.
I wanted to know if there is issue for the below exception.

Microsoft.WindowsAzure.Storage.StorageException: The remote server returned an error: (403) Forbidden.
---> System.Net.WebException: The remote server returned an error: (403) Forbidden.

StatusMessage:Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
ErrorCode:AuthenticationFailed
ErrorMessage:Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Thanks,
