PermanentRedirect Exception: aws-sdk s3 Rails 5

Question

I'm trying to list or retrieve objects from an amazon bucket and I keep getting this error message:

(byebug) resp = s3.list_objects(bucket:'mp3list')
*** Aws::S3::Errors::PermanentRedirect Exception: 
The bucket you are attempting to access must be addressed 
using the specified endpoint. 
Please send all future requests to this endpoint.

I can upload and delete files from the same bucket with no problem.

Does someone know how to specify that endpoint? and where?

My configuration of the s3 bucket:

Bucket: mp3play
Region: Frankfurt
Creation Date:  Fri Dec 09 17:44:39 GMT+100 2016
Owner: aaa

Can list, upload, delete.

aws.rb >

Aws.config.update({
  credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']),
  region: 'eu-central-1'
})

# list buckets in Amazon S3
s3 = Aws::S3::Client.new
resp = s3.list_buckets
S3_BUCKET = resp.buckets[0]
resp.buckets.map(&:name)

S3 = Aws::S3::Resource.new(region: 'eu-central-1')

Add endpoint key to config:

Aws.config.update({
  credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']),
  region: 'eu-central-1',
  endpoint:'https://s3.eu-central-1.amazonaws.com'
})
