I am trying to implement a day to day workflow for myself where ChatGPT fetches data for my to-do list over website. My back-end system dynamically generates a HTML file (no password, just a plain accessible URL from any browser, no tricks) and I would like ChatGPT to fetch its contents for internal work.
But… It is unable to do it. It starts bullshitting me about it returning Internal Error (which is incorrect) or giving me other excuses that the page is dynamic (it is not) etc.
This seems like such a basic thing, why is ChatGPT unable to do it? Why do some websites work, and others do not work?
As an alternative, Gemini has no problems whatsoever fetching related content from that URL.
