AWS S3 IllegalLocationConstraintException Error when using bucket.objects.all()

Question

It is needed to read and download files from AWS S3 (not created by me, it is external S3 resource by others, so i cannot change any bucket policy) i am in Hong Kong (my physical location)

IllegalLocationConstraintException appears. Full Error is shown below (An error occurred (IllegalLocationConstraintException) when calling the ListObjects operation: The us-east-2 location constraint is incompatible for the region specific endpoint this request was sent to.

REGION_NAME = 'us-east-2'
client = boto3.client('s3',region_name=REGION_NAME) 
s3 = boto3.resource('s3',
                aws_access_key_id=ACCESS_KEY,
                aws_secret_access_key=SECRET_KEY
                ,region_name = REGION_NAME
)

bucket=s3.Bucket(BUCKET_NAME)

for obj in bucket.objects.all():
    print(obj)
    print(f'filename : {obj.key} ')
    s3.Bucket(BUCKET_NAME).download_file(obj.key, f'download_from_s3/{obj.key}')

I have tried to do the following but it doesn't help

1. set region_name = 'us-east-2' and add this params
2. Try call the following to look at the bucket info, still face same error IllegalLocationConstraintException

response = client.get_bucket_cors(Bucket=BUCKET_NAME)

result = client.get_bucket_policy(Bucket=BUCKET_NAME)

3. Reach lots of online solution to set the LocationConstraint. But it seems for create bucket, i cannot change the bucket's policy (as created by others)
