Update: Authenticated Access to S3

Hi, I’ve been using Integromat to automatically download the attachments from Trello. It was working fine until past few days it just stopped working. I tried to debug myself through Postman, managed to retrieve the attachment details:
https://api.trello.com/cards/61b17b.../attachments/61b1cb.../

{
    "id": "61b1cb...",
    "bytes": 84045,
    "date": "2021-12-09T09:25:32.087Z",
    "edgeColor": "#fcfcfc",
    "idMember": "5e9c72...",
    "isUpload": true,
    "mimeType": "image/png",
...
    "url": "`https://trello.com/1/cards/61b17b.../attachments/61b1cb.../download/Screenshot_2021-12-09_at_5.25.28_PM.png`",
    "pos": 16384,
    "fileName": "Screenshot_2021-12-09_at_5.25.28_PM.png"
}

With the same OAuth setup, I called the above url but was responded (401) “unauthorized permission requested”
Tried both api.trello.com and trello.com and still didn’t work.

Did I miss anything in the call?
