I was stuck for 3 days and finally, after reading a ton of blogs and answers I was able to lớn configure Amazon AWS S3 Bucket.

On the AWS Side

I am assuming you have already

1. Created an s3-bucket
2. Created a user in IAM

Steps

1. Configure CORS settings

   you bucket > permissions > CORS configuration

   
   
       *
       GET
       POST
       PUT
       *
   
   ```
   
   

2. Generate A bucket policy

your bucket > permissions > bucket policy

It should be similar to lớn this one

 {
     "Version": "2012-10-17",
     "Id": "Policy1602480700663",
     "Statement": [
         {
             "Sid": "Stmt1602480694902",
             "Effect": "Allow",
             "Principal": "*",
             "Action": "s3:GetObject",
             "Resource": "arn:aws:s3:::harshit-portfolio-bucket/*"
         }
     ]
 }

PS: Bucket policy should say `public` after this 

3. Configure Access Control List

your bucket > permissions > acces control list

give public access

PS: Access Control List should say public after this

4. Unblock public Access

your bucket > permissions > Block Public Access

Edit and turn all options Off

**On a side note if you are working on django add the following lines to lớn you settings.py tệp tin of your project **
