Hmm, after looking into it I would suggest that you open up a support case so that the team can further look into what is going wrong.

Here are the steps to open a support case. If your company has someone who manages your AWS account, you might not have direct access to AWS Support and will need to raise an internal ticket to your IT team or whomever manages your AWS account. They should be able to open an AWS Support case on your behalf.
