AWS Storage Add-On Issue

I am receiving an invalid access key error. However, when I go into the cloud storage settings to put in the access keys and save them they revert back to “a” in all boxes.

<Error>
InvalidAccessKeyId
<Message>
The AWS Access Key Id you provided does not exist in our records.

<AWSAccessKeyId>A</AWSAccessKeyId>

</HostId>
</Error>

Can you please help me understand why the access key isn’t “sticking”?
