Cannot create Exchange Account

[ozum]

When I tried to create (connect) a new exchange via API:

POST /ver1/accounts/new

{
  type: "binance",
  name: "Development",
  types_to_create: ["binance_futures"],
  api_key: "...",
  secret: "...",
}

I got error: 'API keys are no longer valid or incorrect. If you have just created this key, please wait 30 seconds and try again.'

Notes:

1. I can connect to 3Commas API and fetch data. So, my connection method is OK.
2. api_key and secret are correct. I tested them in the 3Commas web app, and they successfully created the account. However same api_key and secret do not create the account via API.

Please advise.

Thanks,
