What does HTTP 408 mean?

HTTP 408 Request Timeout means the server waited too long for the client to complete sending the request. This is different from a server timeout (504) — here the server is ready but the client is too slow.

Common Causes

•Slow network connection
•Client took too long to send data
•Large file upload on slow connection
•Server timeout configured too aggressively

How to Fix It

1.Check network connectivity
2.Increase server timeout settings
3.Implement chunked uploads for large files
4.Use a CDN to reduce latency

SEO Impact

Frequent timeouts hurt SEO. Google may reduce crawl rate if your server frequently times out.
