Why is my Instagram post failing?

I am using instagram for business and jotform. I am trying to get make.com to pull responses (including pictures) from a Jotform form and post on Instagram for business. I seem to be having a problem with the picture upload (public url link). I would love some suggestions on what to do. Everything seems to be right except the photo upload issue.

Where is the photo being uploaded? It needs to be publicly accessible (meaning anyone that has the link can see the file) and not from Google Drive or Dropbox.

Are you also using “Create a Photo Post” or “Create a Carousel Post”?

It is in a publicly accessible link.

Can you post screenshots of the scenario and the settings or upload the blueprint?
