File import from s3

Hello, I am trying to import file from s3 to neo4j but I am getting error which is
Neo.ClientError.Statement.ExternalResourceFailed: Couldn't load the external resource at: ''s3 link"
i did the aws configuration as well. Also, I did make the changes in neo4j.conf file which i read in some of the posts.
So what other reason it could be?

have you followed the instructions provided at

Yes I followed that as well. it is not working. Do we need to make s3 bucket public to access the data in neo4j? or is there any way we can access data from private s3 buckets.
Thanks
