API requests to /api/v1/Attachment responds with 403 forbidden

[hmcquaid]

I have had no issue with the Attachments API on any of my other instances of EspoCRM, but one instance in particular does not allow me to Upload attachments or get attachments. my /data/upload folders are configured with 775 permissions on the folders and 664 for files.

URL I am using for my API request: https://<url>/api/v1/Attachment

Any ideas about why I am forbidden to use the Attachments API?

who is the owner?

The owner is "www-data" for all of my folders in my espocrm project. I can upload attachments just fine through the UI.

I recommend checking what message is logged in the log file.
