You refreshed or retried something on roblox.com and got a page that says "429 Too Many Requests". During login it can also show up as "An error was encountered during authentication. Please try again."
Roblox received too many requests from your account or network in a short window, so it temporarily limited more requests. The 429 response is not a ban and does not by itself mean Roblox is down or your device is broken.
| Your situation | Do this |
|---|---|
| Just hit the error | Stop refreshing and wait before one retry |
| It appears during login | Stop retrying, clear Roblox cookies, wait |
| Still blocked after an hour | Test mobile data, then restart your router |
| A VPN or proxy is on | Turn it off and retry once |
| Lasts many hours on every network | Contact Roblox Support |
Waiting is the real fix
429 is a rate limit. More refreshes and login attempts create more requests, so leave the page alone instead of repeatedly testing it. Roblox does not publish whether each retry resets a timer or how long its player-facing limits last.
Close the tab and wait before trying once. Community sources commonly report waits of about 15 to 30 minutes, but the limit can clear sooner or take longer.
It is not a ban either. A moderation action shows a message tied to your account when you log in, while 429 is an HTTP rate-limit response.
What to check if the limit lingers
These steps do not replace waiting. They stop extra requests and help identify whether the limit is tied to a browser session or network.
1. Stop whatever triggered it
Close extra Roblox tabs. If you use an auto-refresh extension, login automation, or another tool that sends Roblox requests, turn it off before waiting.
2. Clear Roblox cookies and browser cache
Clearing site data can reset a stuck Roblox browser session, but it does not remove a server-side rate limit. Clear cookies and cached data for roblox.com in your browser settings, close the tab, and wait before one retry.
3. Test another network
Turn off Wi-Fi and try once on mobile data. If Roblox works there, the limit may be tied to your home network's public IP rather than only your account.
You can then restart your router and wait before reconnecting. Some internet providers assign a different public IP after a restart, but many keep the same one, so this is not a guaranteed shortcut.
4. Turn off your VPN or proxy
A shared VPN or proxy IP carries requests from many people and may already have high traffic. Turn it off, return to your normal connection, and try once after waiting.
5. Contact Roblox Support
Use this only if 429 persists for many hours across more than one network. Contact Roblox Support and describe when the error started and what you were doing.
Seeing 429 in Roblox Studio or from game scripts? That is API rate limiting, not the website block. HttpService allows 500 requests per minute per game server, per the official rate limits documentation. Send fewer requests, space them out, and use delayed retries. An external API may also return a Retry-After header that tells your code how long to wait.
If Roblox fails to launch instead of showing a blocked webpage, follow the fixes for "An error occurred and Roblox cannot continue". If the app opens and then shuts down, use the separate Roblox keeps closing on PC fixes.
