Unable to fetch image from AWS

We are using Strapi version 4, with AWS image upload plugin installed on it. I am able to upload the image from media library from Strapi admin panel and files has successfully reached on AWS S3 bucket. but after upload the image thumbnail is not showing.

I am using getting following error when trying to access the image URL directly in browser:
Access Denied

I am using a private network is there any additional setting that needs to be done to show images?
