Probably, there is no such person in the world who, traveling around the Internet, doesn’t get to pages containing messages like “File not found” or something like that. Let's see what kind of error it is, why it arises and how to deal with it.
What is the "404 File not found" error?
First of all, you need to understand that this type of error relates specifically to surfing the Internet. The simplest explanation is that the requested page was not found.
In principle, errors like “Could not find file” can occur in any “OSes” and in any browsers. As for the varieties and the reasons for their appearance, it is worthwhile to dwell on them in more detail.
Varieties of the "File not found" error
I must say that, depending on the operating system, the browser used, or the requested site itself, the error may contain different syntax. It can be, say, just the message “Error 404”, “404 Error”, “404 Not found”, “404 File not found”, “HTTP 404”, “HTTP 404 Non found”, “404 Page not found”, “The requested URL was not found on the server”, etc.
As you can see, there are a lot of options, but they all boil down to one thing: the browser cannot display the page, presumably located at the given URL. Why? Now we will figure it out.
Causes of error
So, we have a message on the screen of the Internet browser about the unavailability of any web resource - “File not found”. The reasons can be any number.
First of all, as it is considered for some reason, the 404 error is purely client-side and is associated with incorrect request syntax. In other words, the URL (http: // www. And something further) was entered in the address bar with errors. What to do? Yes, just check the spelling of the address.
Sometimes such an error can occur during the process of loading the site when disconnecting the connection (Internet access). It is clear that you need to check the connection or restore it, say, reboot the computer terminal or router. It will not help - you need to contact your provider and find out the reason for the lack of access to the Network.
In some cases, the “File not found” error may also be due to the fact that the requested site is no longer present on this server. In other words, he “moved”, but when accessing the old address, redirection to a new web resource does not occur. What to do in this case? Use any search engine and find it again (at a new address).
How to fix the error using browser settings and network connection
In addition to the quick fix above, you can use the regular page refresh (F5). Who knows, maybe for some reason the browser did not receive the server response on time.
However, a universal method for fixing this type of error (if you do not take into account the option that the requested page is really missing on the server) can be to clear the cache and cookies.
In different browsers, access to such functions is carried out differently, but the essence of this does not change.
A more complicated situation is when, for example, on a computer terminal or laptop, the page does not load, followed by an error message, and everything works fine on a mobile gadget.
Apparently, the computer has the wrong Internet connection settings. It is worth paying attention to the fact that if other devices have access to the resource, the problem may be related to DNS servers. To correct this situation, it is best to contact the service support provider and find out the correct values, which then will need to be written in the appropriate fields of the DNS server settings.
If the error is repeated again and again, this may indicate a malfunction of the server itself, where this page is located, and possibly blocking the content of the site. True, in this case, a warning should be issued either from the antivirus or from the Windows security system in the form of a firewall. Sometimes a firewall may not generate warnings, so it’s worth checking the exception lists both in the firewall and in the browser used. But such situations are very rare.
