No report update since 06/08

Hi,

I use s3stats for more than half years, get issue recently, no report update since 06/08. I first think if it my s3 bucket's issue, and I create new s3 bucket to save log. But when I check the original log s3 bucket, I find the log file is there, but no report created.

Is there any issue/reason for no report update since 06/08?
Thanks.

thanks.
Lora
