Hello, i’m running locally

- akka-stream-alpakka-s3 v2.0.2
- scala 2.12.12
- [localstack v0.11.6](https://github.com/localstack/localstack/releases/tag/v0.11.6)

```auto
docker run -e SERVICES='s3' -e DEFAULT_REGION='eu-west-1' -p 4566:4566 -it localstack/localstack:0.11.6

```

- create bucket with aws cli:

```auto
aws --endpoint-url=http://localhost:4566 s3 mb s3://testBucket

```

- when calling:

```auto
S3.checkIfBucketExists("testBucket")

```

it fails with error:  
`Connection was closed while response was still in-flight`

Am i missing something ?

> alpakka.s3.access-style = path

adding this config to application.conf solved it for me.
