Three reasons why the proxy IP will time out when crawling

  I believe that many of my friends have encountered this kind of situation when using proxy IP crawlers: I have made sufficient preparations, and when I just started a day of crawling work, the prompt “Access to the website address request timed out” appears. This is the case when using a free proxy IP. More frequently.

Three reasons why the proxy IP will time out when crawling

  Then why is there a timeout when using a proxy IP crawler? There are mainly the following reasons:

  1. The network is unstable

  IP timeout caused by network instability often has many situations, which need to be tested one by one to find out. If it returns to normal after changing the network, then your client is unstable; if it returns to normal after changing the proxy IP, then the network of the proxy server is unstable; if the above two methods can return to normal, it means that the client The network of a node in the network of the client and the proxy server is unstable; if it returns to normal after a different website visit, it means that the server of the target website is unstable.

  2. Sending requests concurrently is too large

  The proxy IP timeout caused by too large concurrent requests only needs to test the website access, that is, use the browser to access normally when the proxy IP is used. If it returns to normal, then the concurrency is too large and the concurrency needs to be reduced.

  3. Triggered the anti-climb mechanism

  The test that triggers the anti-crawl mechanism is the same as the test with excessive concurrency. You only need to use the browser to access the website with the proxy IP. If it is normal, then the crawler may trigger the anti-crawl mechanism of the website and you need to change the proxy IP.

  The above is how to determine the reason for the proxy IP timeout. After determining the reason, we can prescribe the right medicine to solve the timeout problem.
