**Title** : _ **Critical Error – ChatGPT Browsing Tool Returns False 500 Errors on Valid URLs** _ **Summary** : The ChatGPT browsing tool returns **false** “ **500 Server Errors** ” when trying to re-access _ **valid, functional URLs.** _ These are _ **not** _ legitimate server errors, but **failures** within OpenAI’s own browsing infrastructure—likely due to _timeout length_ (my guess), proxy issues, or rate limits—misreported as external faults. **Live Repro Case (May 11, 2025):** - User shares a Flipboard article: [My 8 Foolproof Methods to Check If a Social Media Post Is AI or Not](https://www.makeuseof.com/social-media-ai-detection/) - Assistant accesses and analyzes it successfully. - 20 minutes later, user requests follow-up on the same article. - Assistant calls open\_url() and returns: _emphasized text_ Error from browse service: Error calling browse service: 500 - User manually confirms the page is 100% accessible via all standard browsers. This is a false negative and a logic error: the _ **browsing layer is broken** _, not the target page. **Why This Is Critical:** This doesn’t just fail—it lies about the nature of the failure. #NotGood - Users are misled into thinking external websites are broken. - It erodes assistant credibility when it contradicts earlier behavior. - There’s no fallback: cached content, retries, or honest error reporting. - It kills session continuity in research, writing, and fact-checking tasks. - The assistant acts blind but pretends informed—a fatal UX sin. _ **User Predicted This Weeks Ago:** _ “_I would suspect you are getting these errors due to a low timeout threshold or error masking from an internal browser tool. It’s your own backend choking and calling it a 500.”_ **Requested Fixes:**. - **Add retry logic** and **longer thresholds before triggering failures**. - Allow _ **fallback to recent cached content** _ if the page was successfully opened earlier in the same session. - Implement honest error messaging: distinguish true HTTP 500s from internal timeouts or proxy failures **This is not a minor flaw** —it’s a _systemic integrity breach_ that breaks long-form workflows and insults the intelligence of users who verify failures manually. _ **Needs escalation and resolution.** _ ---

This is a major concern that no one is talking about. ---

The ChatGPT web interface does the same and first comes up with random reasons until with some pressure agrees the error is with its browertool. Got everything from unstable tooling, error 500, 503: not safe to open (non-retryable), all while it can access other sites with the same structure on the same server. ---

This started happening two days ago for me, first in a custom gpt I was building and then in the plain chatgpt user interface. the URL in trouble is [https://peoplespalacesf.com/meetings/Planning\_Commission/2025-09-11/transcript.html](https://peoplespalacesf.com/meetings/Planning_Commission/2025-09-11/transcript.html) or anything like it. it is in a public s3 bucket and is static html. no problem with browser access, wget or curl, there is no restrictive access policy. I have filed a bug report ---
