Issue on Heroku

This extension does not work on Heroku. 

We can see product/category images on front end as well as on back-end when we upload product/category images from Magento admin but after some time image URLs are broken on both the front/back-end side but we have those images on AWS S3 but not showing in Magento.

Please let us know the reason where images were gone from Magento.

Thanks
