Log storage in S3 stopped

Hi there,

@Nick-Convox hoping you can help.
Around 1 year ago, logging of our app logs to the S3 bucket stopped.
This is the location I am talking about:
s3://rackname-logs-somecode/convox/logs/rackname-appname/s3/

It used to create files with names like:
2018-09-28-23-19-46-123412341234383B

What configuration do we need to re-enable for logs to be stored there again?

Thank you!
