BlobServiceClient timeout

Question

BlobServiceClient timeout

Lorenz Weinzierl 21

Problem: we are reaching a timeout error with the BlobServiceClient instead of receving a error that shows that the credentials are invalid:

from azure.storage.blob import BlobServiceClient

BlobServiceClient(account_url="sdf.blob.core.windows.net", credential="sdf").get_account_information()

Question: is there any way to validate such credentials without reaching a timeout error?

Hello @Lorenz Weinzierl

Thank you for your post.

As per your case scenario description, I would like to advice you on how to review this in deep , so please see below:

Are you using Private Endpoint to reach your storage?
Did you configure Private DNS for the same?
Did you provide any role permission to this or are you using the owner user account?
Have you tried to use SAS for this storage?
Did you allow your IP address or IP range on the firewall tab on your storage account?

When using a SAS string to access your storage, you can double check this by using Azure Explorer storage app and follow this:

After that you will see this:

furthermore, you will paste your SAS string to this section below:

Finally, you will confirm if the issue is authentication or any other issue on this environment.

I hope that was relevant to keep going with your task.

Have a good one.

Hi @risolis

Let me first try to answer your questions:

Are you using Private Endpoint to reach your storage?

the endpoint we are using is sdf.blob.core.windows.net

Did you configure Private DNS for the same?

no we do not configure this

Did you provide any role permission to this or are you using the owner user account?

credentials are sdf, so an existing domain but invalid access key.

Did you allow your IP address or IP range on the firewall tab on your storage account?

I assume we would need to do this on sdf account in our case which is not ours of course :)

Let me give you some more information on the background of our problem:
We are trying to build a validation logic to check if the credentials in combination with the URL are valid.

During testing, we have tried using BobServiceClient with the account_url sdf.blob.core.windows.net and username "sdf"

BlobServiceClient(account_url="sdf.blob.core.windows.net", credential="sdf").get_account_information()

The problem we have is that instead of returning an error, the API times out after more than a minute.

Hello @Lorenz Weinzierl

Many thanks for that info gathered previously.

I would like to think that this info below can give you some more clues where the issue might be:

    **keyword int max_block_size: The maximum chunk size for uploading a block blob in chunks.  
    Defaults to 4*1024*1024, or 4MB.  
:keyword int max_single_put_size: If the blob size is less than or equal max_single_put_size, then the blob will be  
    uploaded with only one http PUT request. If the blob size is larger than max_single_put_size,  
    the blob will be uploaded in chunks. Defaults to 64*1024*1024, or 64MB.  
:keyword int min_large_block_upload_threshold: The minimum chunk size required to use the memory efficient  
    algorithm when uploading a block blob. Defaults to 4*1024*1024+1.**
