63044: Link to a sample media file returns 404 Not Found

This error occurs when the sample media URL returns 404 Not Found, so Twilio can't retrieve the file. For media and content templates, the sample URL must resolve to a publicly hosted file.

• The media file does not exist at the URL you provided.
• The URL path is incorrect, including the file name, directory, or file suffix.
• If you use a variable in the media URL, the sample path does not resolve to a publicly hosted file.

• Update the URL so it points to the correct file path and the file is available.
• Confirm the link opens in your browser and resolves to a publicly accessible file.
• If the URL uses variables, provide a valid sample path so the combined URL resolves to a publicly hosted file.

• twilio/card
• twilio/media
