Error adding S3 source

I can’t seem to add an S3 source. I have an account with 4 S3 buckets. I can access these buckets via Spark from Databricks and Hortonworks, but I can’t from Dremio. When I add the S3 source and enter the access key id and secrety key I keep getting the error: “Failure while configuring source [S3_new]. Info: Unavailable: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: 93E7CF233799C61B)”

I can use that same access key id and secret key via Spark using Databricks and Spark using Hortonworks and I can connect just fine to S3. Are there additional settings I need to configure?

I can even access the buckets running hdfs commands from the shell prompt to do a file listing.

I can’t seem to enter the access key id and secret via via Dremio.

Can you confirm proper access - https://docs.dremio.com/data-sources/s3.html ?
Another thing to look at is proper bucket permission. I made a post on that topic before here.
Lastly, a copy of server.log would help too
