63043: Link to a sample media file returns 403 Forbidden

This error occurs when the sample media URL returns 403 Forbidden, which prevents Twilio from retrieving the file.

• The media server requires authorization, so Twilio cannot access the file without credentials or a valid token.

• Host the sample file at a publicly accessible URL that Twilio can fetch without authentication.
• If you must protect the file, use a URL that includes a valid access token or another authorization mechanism that allows Twilio to retrieve the media.

• twilio/media
• Protect media access with HTTP basic authentication
• Media subresource
