Authentication failure (401 code)

[giveapps]

Hi team!

Kindly check issue of connection to selectel cloud storage.
Error message:
Could not authenticate: Client error response
[status code] 401
[reason phrase] Unauthorized
[url] auth.selcdn.ru/tokens

We used last version of modx-swift and set following parameters:
AuthServer: auth.selcdn.ru
Container: container_name
service: ru-1
Username: account_username
api_key: account_password

All required access was granting and user credentials are checked.
Customer support of selectel advised to check connection workflow:

Looking forward your answer.
Appreciate your support!
