Cannot Read Uploaded Files & Downloads Not Working

ChatGPT Bugs
1

I’m experiencing persistent issues with file uploads and downloads in ChatGPT Plus.

The Problem:

  • Uploads work, but ChatGPT cannot read or process uploaded files.
  • Downloads do not work—generated files either fail or provide expired links.
  • Attempting to access OpenAI’s file service returns a “ResourceNotFound” error, confirming that OpenAI’s file system is inaccessible.

Troubleshooting:

  • Checked OpenAI’s Status Page (No reported outages)
  • Tested on multiple browsers (Chrome, Edge, Incognito Mode, updated versions)
  • Tried different devices & networks (Same issue persists)
  • Cleared cache & cookies
  • Disabled VPNs & tested firewall rules

OpenAI Support’s Response:

  • Acknowledged this might be a server-side issue
  • Redirected me to the status page, where no issue is reported.
  • Suggested basic troubleshooting, which I have already completed.

Can someone from OpenAI’s technical team confirm whether this is a known issue please, and provide a timeline for resolution?

This issue prevents file-based workflows entirely and needs urgent attention.

No, no resolution yet, I was asked to provide HAR logs for the development team to investigate further, which I did.

Ha . . . .What a surprise. Chat GPT apparently cant do Squat with uploaded files. I suppose if I had a string of numbers say, 1-10 in an uploaded file and asked it to print them it might. It starts reading stuff, does great for a session but, when I go back in and ask it to do the same thing, (read a part of a file and compare it with another file) All of a sudden it cant access the file, or it pulls the wrong data, or it makes up data. ALL the while telling me how “sorry it is” and how “correct I am in calling it out on the error” and "promising to do better (only to do the exact same error again). After struggling for the better part of a day, I converted the PDFs to text and, Guess what? ChatGPT now had trouble reading the straight text that I uploaded. I ultimately gave up. I’m hoping that the Chinese or Musk’s version start offering some other features because, in my opinion, Chat GPT is going down the tubes, and FAST.

Same here. The most recent update seems to have broken the Upload File Parts API.

BTW: I cross-checked Azure OpenAI. That backend still works, using the same API. So it’s definitely an issue on OpenAI’s end.

Same issue over here regarding downloadlinks!

    *< first error occured 10-03-2026 >*

Problem:

  • Clicking sandbox:/mnt/data/… artifact links results in an endless spinner.
  • No file download starts.

My HAR analysis :

-The action triggers GET requests to /backend-api/conversation/…/interpreter/download.

-So far the requests returned HTTP 200.

-Responses had content - type : application/json.

- No file download response / Content-Disposition header was observed.

*I’m guessing* the issue here is the artifact download flow may be returning a JSON/API response instead of a file response**.**
