If you encounter ERR_CONNECTION_RESET in Chrome when browsing a few web pages, this means that the browser can not establish a stable connection or absolutely do not have a website you want to open. While some sites open well, others show this error. Connection reset means that when the data is received by the peer computer, in this case, you can not handle it. This post will show you how to fix error 101, ERR CONNECTION RESET in Google Chrome browser on Windows 10/8/7.

Fix ERR_CONNECTION_RESET Chrome

When you see this error message, you’ll also see the following message:

This website is not available, The connection to example.com was interrupted, Error 101 (net:: ERR_CONNECTION_RESET): The Connection was reset

Here are our suggestions on how you can fix it. Make sure to reload the page after each change you make to find what’s right for you. As usual, I will split the troubleshooting steps into two. First for PC and second for Chrome.

Troubleshoot PC network problems

1] Check your network cable, restart the router and reconnect

Basic tips, but sometimes the cause of the problem. Make sure you check that your cable is properly connected to your computer or router. If you connect via WiFi, be sure to restart your router once. Finally, you choose to forget the WiFi you have connected and then reconnect.

2] Delete Proxy:

  • Hit Windows Key + R and enter “inetcpl.cpl” and hit enter to open Internet Properties.
  • Next, go to the Connections tab and select LAN settings.
  • Uncheck Use a proxy server for your LAN and make sure to select “Automatically detect settings”.
  • Click Ok then Apply and restart your PC.

If you are using a third-party proxy service, please disable it and try again.

3] Delete DNS and reset TCP/IP

Sometimes the site does not work because the DNS in your computer still remembers the old IP. So be sure to Flush DNS, and Reset TCP / IP.

To FlushDNS, run the following cmd command:

ipconfig /flushdns

To reset TCP / IP, run the following command on CMD:

netsh int ip reset resettcpip.txt

4] Increase MTU (Maximum Transmission Unit)

Speed ​​up internet also helps. Here, it means you can increase the MTU (Maximum Transmission Unit), RWIN (TCP Window Receive) parameters.

  • Go to Settings> Network & Internet> Ethernet
  • Note Active Wireless / Wired Network Connection, such as Ethernet
  • Open cmd with administrator privileges.
  • Type the following command in CMD and press Enter:
netsh interface IPv4 set subinterface “Ethernet 4” mtu=1472 store=persitent

5] Disable the AppEx Network Accelerator feature

AppEx Networks Accelerator is known to slow down network connections. Many people report that it slows down the network speed by 70% to 80%. It’s best to disable this feature.

  • Go to Settings> Network & Internet> Ethernet> Change adapter options.
  • Right-click your network and select properties.
  • Find AppEx Networks Accelerator and uncheck it.
  • Save and exit to see if the problem is resolved.

6] Delete WLAN configuration (When connected to WIFI network)

When you connect to many networks, all of them are stored on your PC. Next time you reconnect to that network, it will automatically connect. It is possible that one of the networks has been changed, and it is not connected properly, or it may be disconnected from the network. It is best to delete all WLAN profiles and start new ones.

7] Reinstall the Network Adapter Drivers

If deleting WLAN configuration does not work, it is possible that the network drivers are corrupted. You will need to re-install the network adapters and reinstall the network drivers for best results. Windows Update will immediately download the driver and install the new driver.

8] Disable WiFi Miniport

Hit Windows Key + X and select Command Prompt (Admin).

Type the following command in cmd and press Enter after each command:

netsh wlan stop hostednetwork
netsh wlan set hostednetwork mode=disallow

Exit the command prompt then press Windows Key + R to open the Run dialog box and type: ncpa.cpl

Press Enter to open Network Connections and find Microsoft Virtual Wifi Miniport and right-click and select Disable.

Fix Chrome issues

I would suggest a few things here. This will ensure that if there are any malicious software or installations that are restricting the network, it will be handled.

1] Start your browser in Safe Mode

Just like Windows Safety Mode, Chrome also has Safety Mode where Run Mode does not have any user settings and extensions. You can run it manually or just use the keyboard shortcut to launch Chrome in Safe Mode and see if your issue is resolved.

2] Run the Chrome Cleanup Tool

Run the Chrome browser’s built-in cleanup and malware scanner. It helps you remove unwanted ads, pop-ups and malware, Extraordinary Startup pages, toolbars, and anything else that destroys the experience by hitting the webpage by overloading. pages with memory requirements.

Type in the address bar:

chrome://settings/cleanup

3] Reset Chrome settings

This option is similar to Reset Windows 10. When you reset Chrome, it will return to the default settings during the new installation. It will disable all extensions, extensions and themes. In addition, the content settings will be reset. Cookies, cache, and site data will be deleted.

Let us know which solution works for you to resolve the ERR_CONNECTION_RESET error in Chrome.

 

How to fix 0x8024a223 when updating Windows 10

Updating Windows is quite difficult and risky, not only because of this often encountered many bugs that ordinary users do not understand, but also because of the quality of updates released by Microsoft.

Over the past few months, many users have encountered an error updating in Windows Update and almost do not understand what the error is, one of which is error 0x8024a223. Running the Windows 10 Troubleshooter could have been helpful, but in the case of this bug (and some other bugs) it did not work. End users can not update.

In many cases, the solution is just one of two ways: reset or restart Windows Update.

How to restart Windows Update

Usually, when you try to use Troubleshooter, Windows Update has restarted itself because this is one of the ways that this tool fixes the problem. But you should restart Windows Update manually because it only takes a few steps only.

Press the Windows + R key combination and then type services.msc or click Start Menu and type the same. You will see a list of Windows 10 services.

Now scroll down, find and right click on Windows Update, select Restart. It may take a few minutes to restart this service, if the error is in the service, you will now update successfully. It is not necessary to reboot the machine but it is best to do so to ensure that the service is restarted.

Find the Windows Update service of Windows 10 and restart

Use Microsoft Troubleshooting

Microsoft also has a tool to find and fix other problems when updating through Windows Update without being included in the OS. You can download the link below, it is basically just a wizard to detect and fix errors.

Some users say that this Microsoft-released application actually does fix the problem, so it’s worth a try.

This tool does not change anything on your system since it only fixes the basics, including the entire Windows Update. Rebooting is not mandatory but should be done.

In some cases, errors can be caused by not having enough memory, so make sure you clean up your hard drive to make room for the update files. Do not forget to check that some antivirus software also block updates so please temporarily turn off.

The error may also be caused by the installation of Microsoft’s monthly updates, but in this case it is due to an error in the patch, not necessarily in the Windows service.

How to create USB password

USB is a small, portable and readable tool. These features make it an excellent means of transferring data between computers. However, because of their mobility, they are more easily lost than ever. Therefore, you should always protect the data contained in the USB.

Unfortunately, you can not password protect your USB as you would with a computer or a phone. Your data protection tools work with encryption. If you do not want to invest in a secure flash drive with hardware encryption then you can use the free application to achieve a similar level of protection. The following article will share for you 6 easy ways to set your USB password protection.

1. Save individual files with a password

As mentioned, you can not completely protect your USB without using encryption. However, if you’re concerned about the time-consuming coding process for the entire directory and need a really quick way to protect only selected files, you can simply save those files with a USB password. . Many programs, including Word and Excel, allow you to save files with a password.

For example, in Word, when the document is open, go to File> Info , expand the Protect Document menu, and select Encrypt with Password.

Then, enter the password and confirm it to protect your document.
Then, enter the password and confirm it to protect your document.

There are many tools that can encrypt and password protect your data. However, most require Administrator privileges to launch on the computer. Such tools are not a viable solution if you need to transfer data securely to a computer where you do not have Administrator rights.

Rohos Mini Drive is a tool that will work whether you have Administrator rights or not. Free version can create an encrypted partition and password protected up to 2 GB for your USB. The tool uses automatic encryption with a key length of 256 bits. Thanks to the portable Rohos Disk Browser you install directly on your flash drive, you will not need an encrypted driver on your local system. Then, you can access protected data anywhere.

Click on Encrypt USB drive from start screen of Rohos Mini Drive, select drive, specify a new password and click on Create disk. This will create an encrypted and password protected area on your external drive.

You can open the protected area by clicking the Rohos Mini.exe icon from the root of the USB. After entering the password, Rohos will mount a separate drive and you can access it via File Explorer. To close the Rohos area, right-click the Rohos icon in the Windows Taskbar notification area and select Disconnect.

3. Full USB encryption

VeraCrypt is the successor of TrueCrypt . It is a portable application that runs directly from your USB. Unfortunately, it still requires Administrator rights to operate. It uses 256 bit AES encryption. The free version is limited to 2GB drive size.

VeraCrypt provides encryption using a variety of algorithms, including 256-bit AES, Serpent and TwoFish, as well as their combination. Like the Rohos Mini Drive, it can create a virtual encrypted drive to mount as a real disk, but you can also encrypt entire areas and storage devices.

Download VeryCrypt Portable and install it on your USB. When launching this application, it will show you all the letters of the available disk. Select one and click Create Volume. This will launch the VeraCrypt Volume Creation Wizard.

To encrypt the entire USB drive, select Encrupt a non-system partition / drive and click on Next.
To encrypt the entire USB drive, select Encrupt a non-system partition / drive and click on Next.

In the next step, you can choose from Standard or a Hidden VeraCrypt volume . Using the Hidden VeraCrypt volume will reduce the risk that someone will expose you to a password. Please note that you will format the whole USB if you want to create a Hidden VeraCrypt volume.

We will continue with the Standard VeraCrypt volume . In the next window, click on Select Device … , select your mobile drive, confirm with OK and click on Next.

To encrypt the entire USB drive, select Encrypt partition in place and click on Next. VeryCrypt will warn you that you should have a backup of your data in case something goes wrong during the encryption process. Then, choose Encrypt and Hash Algorithm, you can follow the default settings. Now, you will set the Volume Password . In the next step, random mouse movements will determine the strength of the encrypted cipher.

Then select Wipe Mode . In the last window, you click on Encrypt to start coding. 

The alternative to VeraCrypt Portable is Toucan, a mobile application that allows you to sync, backup and secure your files.

Bonus: Create a password protected archive file

Storage tools like 7-Zip can also encrypt and password-protect your files with AES-256.

Install and launch 7-Zip, then right-click on the file or folder on your USB drive and select 7-Zip> Add to Archive . In the Add to Archive window , select the Archive format and add a password. Click OK to start the archiving and encryption process.

To install SecurStick, download and extract the .zip file, and then copy the .exe file to the USB drive. Running this .exe file will open a command prompt window and browse. Enter the password and click Create to install the Safe Zone.

The next time you open the SecurStick file, a login window to Safe Zone will greet you. Any files you copy into SafeZone are automatically encrypted. Note that closing the console window closes the session on the Safe Zone.

The easiest way to completely migrate SecurStick from a flash drive is to reformat it.

Note : The interface of the software home page can be completely switched to English so you easily find out information about it.

First, you need to format the flash drive with Apple’s HFS + file systemNote that this will delete the entire archive on it, which means you should back up them. From the Disk Utility , select the flash drive and click Erase. In the popup window, select the file format, MacOS Extended (Journaled), and click Erase at the bottom right to reformat the drive.

Now you are ready to create flash drive encryption. Simply right-click on the drive in the Finder , select Encrypt , and then add the password. This process starts immediately and takes place within minutes, depending on the size of the USB drive. In a nutshell, you will have a USB password protected and encrypted.

6. Encrypt USB drives on Linux with Cryptsetup

Cryptsetup is a free feature to set up 256-bit AES-encrypted disks. It is available in the standard Linux repository.

Note : You should not use this tool if you intend to use encrypted files outside of Linux. Moreover, access to encrypted flash drives requires the installation of Cryptsetup.

To encrypt USB drives on Linux, you need to install the Gnome and Cryptsetup utilities from sudo apt-get . If you use Ubuntu, it’s pre-installed on your machine. Next, open Disks from the desktop, find the flash drive and choose to format the drive or partition with the encryption option. At this point, you need to select a password. Note, you must overwrite the whole file.

So, you know how to protect your USB in the simple ways mentioned above. You may find this process to be quite time-consuming and unnecessary, but it is really worthwhile to keep the data stored in the USB safe.
