When a website receives too many requests within a short period of time, it may return an “Error 429” message to the user. This type of error is often referred to as a “too many requests” or “rate limiting” issue.
The exact cause of this error can vary depending on the server configuration and the individual’s or website’s traffic patterns. It is usually triggered by a surge in incoming requests, such as those generated by automated scripts, bot activity, or high levels of user engagement.
To resolve Error 429, users may need to wait for a period of time before making another request, sometimes referred to as a “rate limit reset.” In some cases, the issue can be addressed by adjusting server settings or implementing measures to reduce incoming requests.
