ChatGPT: Download failed / File Not Found

A generated file link cannot be opened or downloaded.

Quick answer

OpenAI lists “Download failed” and “File Not Found” for generated file links. Its troubleshooting guide says those links expire quickly. Use the newest link or ask ChatGPT to make a fresh file; a page refresh does not renew an expired attachment.

Exact message

Download failed / File Not Found

What it means

First separate two questions: did ChatGPT make the file, and can you retrieve it now? A link can expire after a file was created. OpenAI also asks users to test without VPN or proxy and to keep the file under 512 MB. If you use a custom GPT, the same help page says to check that Code Interpreter is enabled for file creation.

What to try

  1. Use the most recent file link in the conversation. If it is old, ask ChatGPT to create the file again rather than repeatedly opening the expired link.
  2. If the new link still fails, compare the file size with OpenAI’s 512 MB limit and test without VPN or proxy.
  3. If you are using a custom GPT, check whether its Code Interpreter capability is enabled. When the failure persists, contact OpenAI Support with the exact error and the time the new file was generated.

FAQ

Why does a file link say File Not Found?

OpenAI says generated files expire quickly. A link from an older message can therefore fail while the chat itself still works. Ask for a newly generated file and open its fresh link promptly. If the new link fails immediately, the age of the old link is no longer a sufficient explanation; record the new error and move to the network and size checks.

Should I ask ChatGPT to recreate the file?

Yes, when the link has expired or the file is no longer available. Make the request specific: ask it to produce the same output again and attach the finished file. Check the contents after downloading. If the task depended on files that are no longer in the conversation’s working environment, you may need to provide those inputs again.

What if a fresh link still fails?

Try without VPN or proxy, and check that the generated file is below 512 MB. For a custom GPT, verify Code Interpreter is on. If a new, small file also fails, tell OpenAI Support when it was generated, which client you used, and the exact wording. Repeatedly refreshing the old link is unlikely to add new information.
