I need to create a new Compute Environment in AWS Batch but it says that it cannot determine region of bucket. Can you help please?

Does the “sequera-virginia-e1” bucket really exist? Seqera has no **u** , so maybe it’s a typo?

@shasha Can you test if the credentials have proper access to the bucket by using the s3 cli? It could be a credential problem.  
When you start filling the form of the CE creation does the bucket appear in the autocomplete list?

@matteofiandesio @mribeirodantas thanks for your comments and hints.  
I added this extra inline policy to the IAM user and this fixed the issue.  
It works now.  
I hope this helps someone else.
