# How to fix timeout errors?

Smart Proxy Manager automatically rotates IPs and retries requests internally
when it receives a blocked page. It also adds artificial delays to ensure
websites are crawl politely (this is often referred as “throttling”).

These mechanics often results in Smart Proxy Manager requests taking several
seconds to be fulfilled, sometimes above a minute.

When you’re crawling a very popular domain in Smart Proxy Manager you may have
to increase the timeout in your HTTP client to ensure these delays are
accounted for. We recommend increasing to 5 minutes (300 seconds) to be safe.

How to do this depends on the particular technology or language you’re using to
connect with Smart Proxy Manager.

If the HTTP client you use to connect to Smart Proxy Manager doesn’t wait long
enough you will start receiving 499 errors. For more details on this error and
