The region in configuration file is ignored when I make a Sign URL Service request.

I have the following in my configuration.yaml:

s3:
  aws_access_key_id: <key>
  aws_secret_access_key: <secret>
  region_name: us-east-2

I am using the Sign URL Service request in a script:

get_snapshot_url:
  alias: Get snapshot URL
  sequence:
    - service: s3.signurl
      data:
        bucket: <bucket>
        key: snapshots/backyard/snapshot.jpg
        duration: 3600

I have confirmed the image exists on my S3 bucket.

The URL I get back gives me the following error:
InvalidRequestThe authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.

I added a log statement to line 239 of custom_components/s3/init.py to log the region being used:
_LOGGER.error("Region %s", entry.data[CONF_REGION])

"Region us-east-1" is printed in the log.

Everything works if I hard code the region as below.

The Put Service was working as expected.

@jritsema This is still a problem, I hard-coded my region of us-east-2 as well, instead of hard-coding it on that line. I changed the default from us-east-1 to us-east-2
