Crawler proxy IP does not work? Commonly reported errors and solutions!

Why do crawler proxy IPs go wrong?

Proxy IP is a common tool when using crawlers, but sometimes you will encounter a situation where it is not working. This could be because the IP is blocked, the proxy service is unstable, or there is something wrong with your code. Understanding these reasons helps us to solve the problem better.

Common Errors and Reasons

When using proxy IPs, common errors reported include connection timeout, 403 Forbidden, and certain specific exception messages. Let's take a look at the reasons behind these errors.

Connection timeout

Connection timeouts are usually due to unstable or unavailable proxy IPs. This can be because the proxy server is overloaded or the IP has become invalid. The solution is to replace the proxy IP with a new one and make sure it is active.

403 Forbidden

If you receive a 403 Forbidden error, it means that the target website has rejected your request. This could be because the proxy IP is blacklisted or the frequency of requests is too high. You can try to reduce the request frequency, or change to a new proxy IP.

Request Exception

Other exceptions, such as `requests.exceptions.ProxyError`, are usually due to incorrect proxy settings or problems with the proxy server. Check your proxy IP format to make sure it contains the correct protocol (http or https) and port.

1. Change Proxy IP: If a proxy IP is not working, the easiest solution is to replace it with a new one. Make sure the proxy you choose is of high quality, preferably verified.

2. Adjustment of request settings: Reduce the frequency of requests and set a reasonable timeout. This reduces the risk of being blocked by the target site.

3. Use of alternate options: If proxy IPs are a frequent problem, consider using other methods, such as using a VPN or randomly selecting IPs directly from a pool of multiple IPs.

summarize

Proxy IP is a powerful tool in crawling, but it also needs to be used wisely. Understanding the common errors and their causes can help us quickly locate the problem and find a solution.
