What is the reason for the failure to use proxy IP

This article will explain in detail the reasons for the failure of using proxy IP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1. The most common mistake: after setting up proxy IP, I can't wait to visit Baidu to check IP.

But found that even Baidu can not open, visit what website can not be displayed, is not very depressed. The proxy IP cannot be accessed because it is not valid. Please change the proxy IP within the validity period and try again.

2. An error that prompts 407 to require proxy authentication after setting, resulting in authorization failure.

Take the first-hand secrecy agent of the IP agent as an example. There are two different authorization modes, which are IP authorization and user name and password authorization for the machine respectively. If user name and password authorization is selected and IP is bound in the background, these are two different authorization modes. You can choose one of the two authorization modes. If you use them together, there will be problems.

3. 403Forbidden, this kind of error is more complicated.

There are many reasons. If you look at it from the perspective of proxy IP, it is an authorization error. For example, if you bind an IP authorization, if you do not bind to the machine IP that uses the proxy, then using the proxy IP will naturally fail, which is also an error.
