In this era of the internet, big data plays a crucial role in various industries, leading to a surge in the number of web crawlers. These crawlers heavily rely on IP proxies, which in turn has fueled the growth of the IP proxy industry. However, many encounter different issues while using overseas HTTP proxies, particularly when accessing target websites, resulting in various error codes. So, what do these error codes, such as "403" and "407," signify? And how can they be resolved?
Let's delve into the reasons behind these two error codes when using overseas HTTP proxies and explore potential solutions:
I. Accessing HTTP protocol websites using overseas proxy IPs: A. Accessing via browser proxy settings:
When prompted with an input box to enter a username and password, if incorrect information is entered and clicking "Login" continues to display the input box, or clicking "Cancel" leads to a "Access Denied" error message.
This indicates an authorization error. Check the authorization settings, whether it's IP binding mode, verify if the IP addresses in the whitelist are correct or if there are bandwidth limitations for dynamic IPs. If it's an account-password mode, verify the correctness of the account credentials.
When the webpage directly displays an "Access Denied" error message.
This implies that the proxy IP is being requested too frequently, causing high concurrency. To address this, reduce the request frequency or consider purchasing a higher-tier package with more IP resources (especially when using short-lived premium proxies). There is also a possibility of accessing a website on the blacklist.
B. Accessing via code using proxy IPs:
Returning a "407" error code.
This clearly indicates an authorization error.
Returning a "403" error with the "Access Denied" message in the HTML.
This suggests that the proxy IP is being requested too frequently, causing high concurrency. To resolve this, reduce the request frequency or consider purchasing a higher-tier package with more IP resources (especially when using short-lived premium proxies). There is also a small possibility of accessing a website on the blacklist.
II. When encountering a "403 Forbidden" error with overseas IP proxies: A. Accessing via browser proxy settings:
When prompted with an input box to enter a username and password, if incorrect information is entered and clicking "Login" continues to display the input box, or clicking "Cancel" leads to the browser's own error message of "Unable to access the website."
This indicates an authorization error. Check the authorization settings, whether it's IP binding mode, verify if the IP addresses in the whitelist are correct or if there are bandwidth limitations for dynamic IPs. If it's an account-password mode, verify the correctness of the account credentials.
When the webpage directly displays the browser's own error message of "Unable to access the website." There are three possible reasons for this:
The proxy IP has expired and exceeded its lifespan.
The proxy IP is being requested too frequently, causing high concurrency. To address this, reduce the request frequency or consider purchasing a higher-tier package with more IP resources (especially when using short-lived premium proxies).
Accessing a website on the blacklist.
