dotnet eb deploy-environment command timeout

Getting a timeout issue when deploying my netcore app to EB. Here are the details :

Uploading to S3. (Bucket: elasticbeanstalk-ap-southeast-2-043897850050 Key: Pavoni/AWSDeploymentArchive_636847158216790790.zip)
... Progress: 10%
... Progress: 20%
... Progress: 30%
... Progress: 40%
... Progress: 50%
... Progress: 60%
... Progress: 70%
Error uploading application bundle to S3: Error uploading to App/AWSDeploymentArchive_App_636847158216790790.zip in bucket elasticbeanstalk-ap-southeast-2-043897850050: A task was canceled.

Start with the `dotnet eb deploy-environment` command and reproduce the reported .NET Core deployment using the supplied S3 upload log. Trace the application-bundle upload through AWS Elastic Beanstalk and S3; done means the deployment no longer times out during upload or clearly reports the underlying failure.
