rclone: Rclone Copy command - Access denied

What is your current rclone version (output from rclone version)?

v1.50

What problem are you are trying to solve?

I’m trying to upload a txt file from aws ec2 instance to s3 bucket with the help of rclone copy filename remote:bucketname. I get 403 forbidden error access denied when I’m uploading a text file to s3 bucket. And i tried to add checksum to the above command –ignore-checksum it’s giving me the same error.

Note I am able to upload the txt file with aws commands aws s3 cp txtfile buckname --sse aws:kms

How do you think rclone should be changed to solve that?

Need aws s3 Proper documentation on how to upload file with encryption and without encryption.
