The inability to open the required page on the Internet is one of the most common problems. The name is correct in the address bar. A reasonable question arises as to why the site, which is so necessary, does not open. There can be many reasons for such a problem, ranging from visual defects to internal software failures.
- Checking Simple Settings
- Internet operation
- Viruses and computer protection
- Browser operation
- Diagnostics of complex settings
- Hosts file
- TCP / IP Protocol Activity
- DNS server problem
- Registry fix
- Browser proxies
Checking Simple Settings
There are elementary causes that can be corrected without resorting to deep adjustments. These indicators are based on many factors, but before considering them, you should carefully read what is written on the open page. In some cases, the Internet provider itself may prohibit the transition to the site. The reason for this may be the lack of a certificate or domain signature.
The main reason that the given address stopped opening may be the lack of the Internet. Diagnose by checking the connection of the network cable to a laptop or computer. When the wireless network is configured, the Wi-Fi coverage is checked and the preferred network is selected.
The reason for the restriction of the Internet connection to the device may be a router or service provider. To check the router, you should look at all the network cables leading to the router, and then reboot the device.
Another control method can be opening an online program, for example, Skype. If the icon on the panel is green, then the Internet connection is present, and the problem is different.
Viruses and computer protection
Even the smartest latest-model machine with the latest system is not immune to malware. They enter the computer in different ways, and here are some of them:
- Installing unlicensed or questionable software.
- Connecting to a laptop via USB unverified flash drives or smartphones.
- Connecting to an unfamiliar Wi – Fi network.
- Downloading unverified files or extensions to the browser.
- Referring to unfamiliar sources on the network.
Once in the device, malware can adversely affect the operation of applications and the system as a whole. Once in the browser, they change the extensions, redirecting to the phishing scam site.
You can see this if another name appears in the address bar or is similar to what it should be. If a problem arises, you need to install an antivirus on your computer and scan all disks with a deep scan. If the program detects suspicious files, they should be deleted immediately.
Each system on a device has its own anti-malware protection called a firewall or firewall. Often, such a firewall lists objectionable and even harmless sites.
If no dangerous software is found, but still some sites do not open in the browser, then disabling the defender Windows and antivirus will help. But it must be borne in mind that the device may be at risk due to online transitions in the browser.
Factors of why some sites do not open in the browser are its malfunctions. They can arise for the following reasons:
- The browser is protected from uncertified sites or unsigned.
- The saved page icon is out of date and the link is not available.
- Malicious extensions installed.
- The site does not function due to technical reasons.
To resolve the issue with the browser, you must try to enter the link manually. If the problem persists, then you need to remove all previously outdated extensions and clear the cache. Before this procedure, save all bookmarks through a mail account or to a file.
Each browser has its own settings and protection against harmful sites. If the page fails to display, you need to open it in another browser or on a smartphone. If during these manipulations everything is displayed, then the point is in the browser itself, in which it is necessary to understand the settings.
Diagnostics of complex settings
System debugging of files is not difficult, just follow the instructions. Some of the configurations responsible for opening the desired site are hidden, but with a number of manipulations it is possible to get them and edit them to achieve the result.
When visiting Internet pages on a computer, all information about the search status and history is saved in one text document 'Hosts'. It often contains viruses that replace the entries necessary for working on the Internet.
By default, the file is located at: for Windows 7, 8, 10 C: \ Windows \ System 32 \ Drivers \ etc \ hosts open it using the Notepad program. If the operating system is installed on a different disk, then it is enough to change the first letter. If you can't find it manually, you can use the search by specifying 'etc' in the line. This is the folder where the file is located.
Having opened the document, you should view the bottom line and delete the suspicious entries, and then commit the corrections by clicking on the 'File' tab and selecting the 'save' option.
There are situations where 'Hosts' cannot be edited. Then the following problems are encountered:
- There are 2 documents in the folder. In this case, you need to find the original file and modify it. The fake virus changes the extension to 'txt', the real one does not.
- No file at the specified address. This means that the virus has disguised the document and there is no way to detect it in the usual way.
You can see the document by going to the 'Properties' folder, clicking the 'Service' option in the tab and choosing the type of folders. Uncheck the 'Show hidden files and folders' option, then confirm the action with the 'ok' button, saving the result. After these manipulations, the file should be displayed, and it is possible to edit it.
If after these actions the user cannot open the site, then there is a deeper method for decoding the file, which is carried out through the command line. When you press 'Win + R', the option 'Run' is displayed, into which you need to drive 'cmd'. In the window that appears, type 'route – f', then restart the device, and the site should load.
TCP / IP Protocol Activity
The place where IP addresses are stored and configured is called TCP / IP and is directly connected to the network. Viruses or malware can cause the protocol to malfunction by making changes. Therefore, you should check this option as follows:
Open the 'Network connections' folder, move the cursor over the icon of the current reception selected for editing. By clicking the button, open the right menu and click on the 'Properties' tab.
For the 'Networks' option in the 'Components' heading, check the box next to the Internet protocol with version 4 or 6. If the IP address has been changed, then it must be configured for the IP v 4 protocol. The actions are as follows:
- In the TCP / IP protocol window, check the box that the configuration and delivery of IP components occurs automatically. Do the same with the DNS server below, saving the changes.
- In the 'Advanced' tab there are IP parameters, where you should tick the 'automatic receipt' checkbox next to all the characteristics. Enter the value of the device address in the 'IP address' and 'Subnet mask' fields.
When changing the IP address for the IP v 6 protocol assignment command, do one of the following:
- Check all options to 'get settings automatically' from service provider in DHCP. Save the result by clicking the 'OK' button on the monitor.
- Assign an IP in the IPv6 address fields, where you need to enter the subnet prefix digits and the default gateway with the device address parameters. Fixing the actions by clicking 'OK'.
DNS server problem
In many cases, ISPs will automatically transmit DNS. But more often than not, the pages do not open when the address is entered. In order to set the correct parameters and the statistical DNS address, you can perform the following actions, which are calculated for Windows:
- On the panel, select the 'Internet Connection' icon, go to 'Network and Sharing Management' or 'Local Area Connection' for Windows 10 'Ethernet'. Find the column 'Change adapter settings', click on the icon, selecting 'Properties'.
- For Wi-Fi connection, go to the 'Wireless Network Connection' tab. Next, the item 'Internet Protocol Version 4 (TCP / IPv 4)' is considered, where you need to go to 'Properties'. Check the box next to the column 'Use the following DNS server addresses' and enter the numbers: 220.127.116.11, 18.104.22.168. Then commit the changes.
In the same way, it is possible to edit DNS by changing the IP addresses in the settings of the router or mobile devices.
The functionality of the database of settings and created profiles, accounts, saved passwords, interaction with the installed program is the registry. Cleaning it will remove unnecessary spam, unnecessary shortcuts, traces of deleted programs, etc. But at the same level, the storage can contain malicious files. There are two ways to get rid of unnecessary garbage:
The keys used Win + R call the line 'Run' for Windows 7 and 8, and in version 10 it is called 'Find'. The word 'regedit' is hammered into it and the search for this folder is carried out. Then click on the found file.
In the window that opens, you need to find a tab with the name HKEY _ LOCAL _ MACHINE, opening it in a hierarchical sequence. Find SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Windows, and in the final section click on Applnit _ DLLs. This volume has no parameters. If, when opening it, other text or side characteristics are noticed, they should be deleted and saved.
An alternative and less troublesome way is to clean the registry using programs. One of the most common is 'CCleaner', which optimizes system performance by removing garbage. Install the application and fix the problem in just a couple of taps. After installing and running the utility, go to the 'Registry' tab, check all possible problems and start the analysis. After detecting complications, the program will ask you to fix them, which must be done.
Malicious files residing on the device can change the 'Proxy' settings and server parameters. You can fix the problem by reconfiguring the utility. How to do this should be analyzed using the example of the popular Yandex browser:
- Launch the browser with the 'Alt + P' keys, after loading you should enter the 'Settings', which are in the menu on the right.
- Scrolling through the options, at the very bottom, open the 'Advanced settings' column, find the 'Change proxy server settings' button.
- If the values are set manually, and the user did not do this, then a malicious program has worked. In this case, check the boxes opposite the 'Automatic retrieval of parameters' item.
- The next step is to check the computer for viruses by scanning the system. Clears the browser history and cache, freeing it from garbage. For better browser performance, uninstall and reinstall it, then restart the device.
In all known browsers the 'Proxy' configuration system is identical. After checking all these parameters, the question of why the browser does not open some sites will disappear, and the problem will be resolved.
