Connect to AzureBlobStorage from AzureServiceFabric stateless service

I have a stateless service running on Service Fabric, it's behind a corporate proxy.
I'm trying to connect to Azure to upload some images to blob storage, but is not working. Is it possible to set Service Fabric proxy or maybe there are other solutions ?

When I'm trying to upload a image :

await blob.UploadFromStreamAsync(fileStream);

Exception thrown:

InnerException = {System.Net.Http.WinHttpException (0x80072EE2): The
