I have an issue uploading a large file to my azure storage blob thru azure storage explorer. The file is approx. 160GB. [155188-errorlog.txt][1] I have added part of the errorLog, some of the lines in the beginning and some in the end. Anyone an idea why it is not working?
Not sure what solved it. But a retry with a new SAS token that also had 'Delete' rights resulted in a successful upload.
Looks like it's a timeout, and I too have personally experienced this issue with large files.
You can do below,
@Maarschalkerweerd, Luuk van Welcome to Microsoft Q&A Forum , Thank you for posting your query here!
Based on the error log : AuthorizationPermissionMismatch|This request is not authorized to perform this operation using this permission.
SASAuthorizationError : Issue could be related to SAS request that failed due to unauthorized access of data or an authorization failure. Can you regenerate the SAS token and try again
Uploading files to blob endpoint Azure storage account via Storage Explorer and command line is failing with error "Response Status: 403 This request is not authorized to perform this operation using this resource type."
Resolution
Create a valid SAS token with permission to the targeted resources e.g. containers and objects. Can be achieved via portal, Storage Explorer etc. Create a user delegation SAS
Tip: Create SAS with an expiry well before the actual start time, UTC format. Why? SAS takes time to kick in.
If the issue still persist, It could be Insufficient permissions to access data abstraction.

Hi Sumarigo,
I have tried to upload a small file (2mb) which works fine, which makes me believe it is not a SAS token or role assignment issue. Correct me if im wrong.
Any other ideas?
@Maarschalkerweerd, Luuk van May I know your block size?
I assume the upload is failing is because the number of blocks (102400) in which you are splitting your blob is more than maximum number of blocks allowed (50000) in a block blob.
To fix the problem, please increase your block size from 1MB to 4MB (or more depending on your internet speed). That way your number of blocks will be around 25000.
What you need to do is essentially change the following line of code:
var blockSize = 1024 * 1024;
to
var blockSize = 4 * 1024 * 1024;
The basic idea is to keep the number of blocks in a block blob to be less than 50000.
To learn more, please see this: https://learn.microsoft.com/en-us/rest/api/storageservices/put-block#remarks.
Upload large amounts of random data in parallel to Azure storage
Over time, the maximum upload size has increased. This article states :, the Maximum blob size (via Put Block List) is approximately 190.7 TiB (4000 MiB X 50,000 blocks) for Version 2019-12-12 and later. The referenced doc gives size limits for other versions as well.
If the issue still persist, I would love to work closer on this issue

I`m absolutely surprised on these logical facts:
Azure its from microsoft
Azure Storage Explorer app is from microsoft too
but its own tool can`t upload an file to its own server, what i supposed to do? KKKKKKKKKKK create my own an software to simply upload files?
