S3 backup silently failing

Hello, I am using the built-in s3 backup functionality in ERPNext. I have inputted my bucket name, access key, region, email address, etc. I have left the endpoint URL as the default as I am using AWS S3. It creates the bucket successfully when I save the s3 settings and does not produce any visible error. When I press the “Take Backup Now” button, it produces a popup saying that the backup was successful and I receive a similar email. Despite this, my bucket is still empty after trying to create a backup. Is there any further configuration that is required. I have also tried to install boto and filechunkio through pip, in case those packages are required.

Could this be related?
