Error 429: Too Many Requests (ERR_TOO_MANY_REQUESTS)

192 views
Updated February 22, 2026

Quick Fix

Refresh the page after a few minutes. If you’re using an API, add a delay between calls. Clear browser cache or use incognito mode to bypass rate limits.

What it Means

HTTP 429 signals that the client has sent too many requests in a given time window. The server is protecting itself from overload or abuse and temporarily blocks further requests.

Possible Causes

  • 1
    Sending too many requests to a server in a short period
  • 2
    API rate limiting rules being exceeded
  • 3
    DDoS protection triggers
  • 4
    Browser extensions or scripts making repeated calls
  • 5
    Automated bots or crawlers

How to Fix

    Step-by-Step Solutions

    1. Identify the source of requests

      Open your browser’s developer tools (F12) and look at the Network tab to see which URLs are being hit repeatedly. This helps pinpoint if an extension or script is the culprit.

    2. Adjust request frequency

      If you control the code, add a delay between requests or batch them. For APIs, follow the documented limits and implement back‑off logic.

    3. Implement retry logic

      Use libraries like axios-retry or fetch‑retry to automatically retry after a delay when a 429 is received.

    4. Clear browser cache and cookies

      Sometimes cached credentials or cookies trigger rate limits. Clear them via Settings > Privacy > Clear browsing data or use incognito mode.

      chrome://settings/clearBrowserData
    5. Check server‑side logs

      If you own the server, review access logs to confirm the rate limit is being applied and adjust thresholds if needed.

    Commands You Can Try
