During the process of web scraping, it's not uncommon to encounter errors, especially when using IP addresses. Improper usage or low-quality IP addresses can lead to failed requests.

Below are some common error codes encountered when using IPs in web scraping and their respective causes:

·Error Code 401 (Unauthorized)

When the error code is 401, the webpage requests authentication, typically occurring when login credentials are required to access the page. Users accessing the page with an IP may be redirected to a login window.

This error usually happens because the IP address has not been authorized in the whitelist, or there is no binding with a fixed IP authorization. To resolve this, users should rebind the whitelist IP authorization and try accessing the page again.

·Error Code 403 (Forbidden)

Error code 403 is one of the most common codes encountered by web scrapers, indicating that the server has denied the request. This often occurs when the scraping frequency is too high, resulting in excessive pressure on the target server.

Consequently, the server perceives the IP of the scraper as abnormal and blocks access. In such cases, users can resolve the issue by switching to a new IP address.

Understanding these common error codes and their solutions is crucial for successful web scraping endeavors. By addressing these issues promptly, users can ensure smoother and more efficient scraping processes.
