ChatGPT’s “Too many concurrent requests” error: what to try first

By Chatbot Daily

If ChatGPT shows “Too many concurrent requests,” pause new submissions, check OpenAI’s service status, then retry with just one active chat. If it keeps happening, work through the session checks below rather than repeatedly clicking Send.

“Concurrent” means happening at the same time, but the message alone does not establish which requests are overlapping or where the problem lies. OpenAI’s general ChatGPT troubleshooting guide does not list this exact message or provide a specific concurrent-request allowance or reset timer. The steps below apply its broader guidance, with a single-chat check to help isolate the problem—not a guaranteed fix.

1. Check for a service incident

Open the OpenAI status page and look for incidents affecting ChatGPT or the feature you were using. If a relevant incident is active, follow its updates before changing your browser settings.

A healthy status page does not rule out your problem: OpenAI reports aggregate availability, not a guarantee for each account.

2. Retry once, without overlapping work

As a practical isolation check, stop submitting prompts in other ChatGPT tabs or devices and use one chat for the retry. This tests whether the error persists without deliberately overlapping requests; it does not establish that open tabs caused it.

If a response is also stuck generating, OpenAI recommends this sequence:

1. Wait 30–60 seconds to see whether it completes.
2. Select Stop generating, then Regenerate.
3. If it remains stuck, start a new chat and resend your prompt.

That wait is guidance for a hanging response, not a documented reset time for the concurrent-request error. Save your prompt before refreshing or leaving the conversation.

3. Isolate a browser, app or network problem

If there is no relevant reported incident and a single retry fails, follow OpenAI’s general troubleshooting steps, testing after each change:

• Reload the session: hard-refresh the browser page with Ctrl/Cmd + Shift + R, or restart the app. Then try signing out and back in.
• Try a clean browser session: use a private/incognito window with extensions disabled, or another browser. If that works, check extensions and clear the affected browser’s cache and cookies.
• Compare connections or devices: try another network or device. OpenAI also suggests disabling VPNs, proxies and secure DNS tools when troubleshooting. On a managed work network, ask your administrator rather than bypassing required security controls.

A successful comparison helps narrow the next step; it does not prove a particular cause. Do not change your subscription based on this message alone—the wording is not enough to identify a plan limit.

When to stop troubleshooting and contact support

If the error persists across browsers, devices and networks, stop repeating the same checks. Contact OpenAI through the chat bubble at the bottom-right of its Help Center, as described in its support instructions.

Include:

• The exact error text and a screenshot with private content removed.
• The date, time and time zone, plus the steps that trigger the error.
• Your account email and plan, selected model, and whether you used the web, desktop or mobile app.
• Browser/app and operating-system details, plus the checks you tried.
• The conversation URL or ID, if available.

OpenAI’s troubleshooting guide also requests browser console errors with timestamps and a HAR network recording for persistent issues. Follow its linked support instructions, use a sanitized export where available, and review the recording before sharing: HAR files can contain sensitive data. Share diagnostics only through your support ticket, and never share passwords or one-time codes.

If you mean an API “429 Too Many Requests” error

That is a separate troubleshooting path. OpenAI’s API guidance says to inspect the error details first: a 429 can indicate a temporary rate limit, exhausted credits, or a spending or usage limit. Temporary rate limits call for paced requests and delayed retries; billing or quota errors require addressing the reported limit. Browser cleanup is not the remedy for those API limits.
