Access was denied by S3 when using public buckets

I created a new S3 bucket, set it as public and allowed list/read ACLs to public.
I created corresponding new data lake with “No authentication” and I added the bucket into the list of public buckets.
When I click on bucket in web UI, I get an error.
In the log I can see:

2021-09-06 15:00:59,598 [qtp267063122-109] INFO - User Error Occurred [ErrorId: 3e89d247-02b6-49a5-9797-b44237aac742] 
com.dremio.common.exceptions.UserException: Access was denied by S3

I can’t see what S3 operation is rejected in the Dremio log.

Please, help me to make this (demo) scenario working.
