Conclusion
We hope that everything worked out for you and you can install plugins for Chrome. If nothing helped, try reinstalling the browser, in some cases this method is like a lifeline.
Software maker Google constantly offers users new features for its browser through extensions downloaded from the Chrome Web Store.
However, sometimes problems arise when installing such plugins. One of the most common is the “Network failed” error that occurs during the download and warns of an allegedly missing network connection.
To eliminate it and be able to use the extensions again, you should find out the reason for the message.
Causes of the problem
- Cessation of some extensions. You can determine that this particular reason caused the problem by successfully downloading another plugin;
- An outdated version of the Google Chrome browser;
- Remote folder Downloads;
- Changing the system hosts file.
The first variant of the reason does not require any action on the part of the user. For the second, you need to update Google Chrome to the latest version. The deleted directory should be restored. And the hosts file is returned to its original state.
Browser update
The first step to take to fix the problem should be to try to update Chrome to the latest version. After all, if you leave an outdated version of the browser, the problem will be not only the inability to download plugins, but also other problems. For example, incorrect display of sites or a multimedia file that does not start. In most cases, the update occurs automatically, but if this does not happen, you will have to perform the necessary steps for this manually. 
You can enable Google's browser update using the registry editor. To do this, perform the following steps:
After clicking the "OK" button, the changes in the registry will be saved. Restarting the browser will ensure that the new auto-update settings are applied and the problem message will stop appearing. Although the registry editor may not have the desired item at all. And, therefore, the issue will have to be solved in other ways.
Changing the hosts file
The next way to get rid of the error in Google Chrome is to restore the hosts file to a state that will allow plugins to run. At the same time, it is advisable to make a copy of it - if something goes wrong, the changes can be undone. To fix a file, you must first find it. One way to search (if you don’t want to do it in system folders) is to open the Run window and enter the notepad %SystemRoot%\system32\drivers\etc\hosts command. The second is to enter the address C:\Windows\System32\drivers\etc in the address bar of any open folder.
Now you need to make changes to the file:
If the browser has been updated and the hosts file has been restored, but the extensions are still not installed, it is worth trying another way to solve the problem. It occurs because of the remote Downloads folder located in the My Documents directory. By returning the folder back, naming it with the same name and selecting it as the download location, you can restore the path for moving data from the network to the computer. Sometimes it also helps to sign in to your Google account and install plugins on behalf of an already authorized user.
After using all the options to resolve the error with the network in the browser, you can restore the plug-ins and continue to improve the functionality of Chrome with their help. If these steps did not help, the program is not just updated, but removed and reinstalled (by downloading the latest version from the official website of the developer). After that, the browser can work normally again. And the message stops appearing when you try to load the plugin.
Probably, many users of the Google Chrome browser have already encountered one common problem when, when you went to the Web Store online store, you could not get a single application.
And it usually looks like this: the user clicks on the “Add to Chrome” button, after which a dialog box pops up in which you need to put your consent to download the extension, and after that ... no download occurs. Downloading will not be carried out, and, of course, installation, too.
A few basic ways to solve the problem with installing extensions in Google Chrome
Faced with an identical problem, we decided to follow the same procedure on other devices (the download was originally done on a personal computer), and noticed that the result came out the same.
From this we concluded that the problem is not in the Internet connection, not in the devices themselves, but in the operation of Google servers. In principle, many holders of online sites suffer from such a misfortune, so we decided to just wait a bit until the system was put in order.
After a week of tedious waiting, the problem remained in place. They did not write to the technical support service, because it was already clear that the administration knew about the error. We engaged in an independent search, and finally found the “root of evil” - the whole trouble was not in the server, but in the Google Chrome browser.
What to do if you receive an error "Internet connection is not established" (Network failed) in Google Chrome
From time to time, the Google Chrome browser may give a Network Failed error when you want to install Adblock or some other extension or add-on. 
What measures to take if the installation of extensions in Chrome does not occur
In most cases, this error disappears immediately after the user reinstalls Google Chrome or installs an update for it. Google Chrome usually always updates without your participation, however, if automatic download does not occur, then you will have to activate this function manually.
Google Chrome browser update is usually enabled using the registry editor. To open it, you just need to hold down the Win and R key combination. 
A command will appear in front of you, in the field you must enter the word “regedit”, and then click on the OK button.
Your attention will be presented to the editor window. 
Errors when installing extensions for Google Chrome from the app and app store are not uncommon. Many users are notified of similar errors in their browser windows.
In the latest versions of Chrome, they are much less common than before. However, users continue to complain about such problems and cannot properly install any. Therefore, we offer you options for solving such a problem.
Problem 1– Wrong date and time on the computer. This can cause errors when installing extensions from the store. Check if the date and time on your computer is correct. If not, then correct these data to the current ones, restart the computer and try installing the extension again.
Problem 2– Compatibility mode enabled. To disable it, right-click on the browser icon on the desktop, open Properties and go to the Compatibility tab.
And there if near the item “ run the program in compatibility mode for:” is checked, just uncheck it and click OK to save the settings.
Problem 3- Blocked by antivirus. It is also possible that the antivirus on your computer perceives the extension as potentially unwanted. In this case, just turn off the antivirus while installing the extension in Chrome, and then turn it back on. But be careful, because by turning off protection, you expose your PC or laptop to the danger of catching some kind of virus.
Problem 4– Long uncleaned browser cache and cookies. In this case, everything is simple. Clear all cache and cookies in your Chrome browser, restart and retry the installation. To clear browsing data, press Ctrl+Shift+Delete.
Problem 5- extra data in the Hosts file. This file is quite often affected by malware that prevents access to the Internet, certain sites, including the installation of applications for Chrome. Therefore, you need to check if there is extra information in this file. See below for how to do this.
How to clear a fileHOSTS:
- Go to drive C à Windows folder à System32 à drivers àetc à Hosts file.
- Opens this file with notepad.
- And remove everything after:
# Copyright (c) 1993-2009 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1localhost
In addition to these lines, this file should not contain anything else.
Problem 6- no downloads folder in My Documents. If it is not there, then just create and specify the path to download files there.
If none of the above helped you and the extensions are not installed in the Google Chrome browser, then we recommend downloading the Chrome cleanup program from Google from the official website - Download. This program will remove all programs and applications on your computer that interfere with the normal operation of the Chrome browser.
A complete uninstall and reinstall of Chrome may also help.
