Today there are quite a few usersmodern computer systems based on Windows, which are familiar with the concept of a proxy server or at least heard about it. Let's see what it is and why there are situations when the proxy server does not respond.
Если говорить простым языком, прокси-сервер is a specialized service that allows you to connect to the Internet or local area network through the so-called indirect (indirect) requests.
In other words, the proxy server acts asmediator between the user of the computer terminal and the requested resource. As is already clear, it is not at all necessary that he be located exactly on the World Wide Web. But very often you can meet the appearance of problems related to the fact that the proxy server is not responding. Now we consider the most frequently occurring situations and methods for their elimination.
As a rule, the proxy server does not respond mainly when using incorrect settings. It would seem that the addresses are entered correctly, but at one point the connection stops working. Why?
This is often due to the wrong orforced shutdown of Windows, for example, in case of a sudden power outage (in cases when there is no uninterruptible power supply unit), shutdown of some system services and applications when the OS hangs, etc. At such times, proxy settings simply have the ability to “fly”. But you can fight this, and even very successfully.
In some cases the problem is thatThe proxy server is not responding, it may be due to its own health. This may be a temporary maintenance, an update of software components, and more. And this is not to say that if the provider service does not provide connection services using a proxy, then it is absolutely meaningless to configure its parameters.
Для начала посмотрим на основные настройки proxies that are called in the advanced properties of the default web browser. For standard Internet Explorer or Edge (Windows 10), these settings are configured through the standard Control Panel.
We will proceed from the fact that the provider is stilluses proxy. If the proxy server does not respond, Windows 7, for example, or any other modification simply does not recognize its actual address when trying to establish an intermediate connection.
What to do in this case? Yes, just enter the correct values of the addresses provided by the provider when the terminal is connected to the local network or the Internet.
About local networks should be said separately.The fact is that failures, even those when the proxy server does not respond, Windows 8 can also interpret in its own way. This, incidentally, applies to almost all the latest versions of Windows, starting with XP. Pay attention to whether the use of a proxy for local addresses is enabled. If there is a check mark in front of this item, it is strongly recommended to remove it. Quite often, the problem arises precisely because of this, since the system does not address the address of the proxy server itself, but the identifier of another machine connected to the local network. Although such addresses, in theory, have nothing in common, nevertheless, Windows versions of all versions are not protected from such failures.
With anonymous resources on the Internet,representing proxy servers that allow you to change or hide the real external IP address of the user's computer when surfing the Web, the situation is somewhat different.
There are mostly connection errors occurprecisely because of the problems of the resources themselves. This is often manifested in the fact that the browser reports that the wait time has elapsed (gateway timeout error 504). This means only that the requested resource, which can work either as a proxy server or as a gateway, did not receive a response in time from a server that is higher in the connection hierarchy.
Here you can do the simplest way - justrefresh the page, and as a last resort (if you are sure that the resource is working) just reload the system. Perhaps, sometimes it may require disabling the antivirus or firewall or adding the site itself to the list of exceptions, because the antivirus and firewall are capable of blocking some sites that they consider suspicious.
Basically, we looked at the most frequent situations.and the simplest methods of correcting them, just without going into the technical side of the issue. Separately, it should be said that in most cases the lack of communication with proxy servers is not associated with any critical disruptions in operating systems. Rather, it is a special case.
It's not even the user settings, butin the performance of the resources of this type, especially in the case of the use of anonymizers. Actually, as can be seen from the above material, and problems can be solved quite simply. Sometimes you even need to just check whether the network connection and access to the Internet is active, and it also happens that the icon in the system tray shows that the connection is active, but in fact it is limited or absent altogether (most often with respect to connections based on Wi-Fi connections).
