Question
NBU doesn't see S3 buckets while they are created and can be seen via cloud provider's web-Interface
Answer
I faced situations when local Cloud provides give incorrect region name in the documentation. You can check it with s3cmd utility. It's very easy to configure and after that you can get list of all buckets and check if the bucket has correct location:
[root@centos ~]# s3cmd ls
2021-04-28 09:17 s3://nbubucket
2021-04-28 09:20 s3://nbudata
2021-04-19 15:32 s3://vms
[root@centos ~]# s3cmd info s3://nbubucket
s3://nbubucket/ (bucket):
Location: us-east-1 <-- We need this value to use in the "region" field
Payer: None
Expiration Rule: none
Policy: none
CORS: none
