  2. Go to Connections tab, and then to LAN Settings.

  1. Go to this location: C:WindowsSystem32driversetc.

6. Renew DNS and IP

And the last thing we’re going to do is renewing DNS and IP Address. DNS cache could also cause a ‘connection timed out’ error, so we’re going to clear the cache, just in case.

To reset DNS cache, and IP address, do the following:

  1. Right-click on the Start Menu, and choose Command Prompt (Admin).
  2. Add the following commands, and press Enter after entering each one:
  • ipconfig /flushdns
  • ipconfig /registerdns
  • ipconfig /release
  • ipconfig /renew
  1. After the process is finished, restart your computer

You may also consider keeping your IP renewed each time you go on the web by installing a reliable VPN tool. Get now Cyberghost VPN(77% flash sale). It protects your PC from attacks while browsing, masks your IP address and blocks all unwanted access to your computer. 

5. Disable problematic extensions

Many users use various extensions, but sometimes your extensions can interfere with your browser and cause Connection timed out a message to appear.

To fix the problem, you need to find and disable the problematic extension by doing the following:

  1. In your browser click the Menu icon in the top right corner. Choose More tools > Extensions.
  2. List of extensions will now appear. Disable all extensions by unchecking the Enabled checkbox next to the extension name.
  3. After disabling all extensions, restart your browser and check if the problem still appears. If not, you’ll have to enable extensions one by one until you find the one that is causing this error to appear.

Users reported that HTTPS Everywhere extension was the cause for this problem, so if you use it, be sure to disable it and check if that solves the problem.

If you use the problematic extension frequently, update it to the latest version and check if that solves the problem.

6. Reset your browser to default

If you’re getting Connection timed out a message, you might want to try resetting your browser settings to default.

9. Make sure that you’re using the 64-bit version of your browser

Most PCs today support 64-bit architecture, and in order to achieve the maximum performance, it’s recommended to use 64-bit applications on your PC.

Users reported the “Connection timed out” message while using a 32-bit version of Chrome on a 64-bit Windows.

To fix the issue, we recommend to remove your browser and install the 64-bit version instead. After doing that, the problem should be completely resolved.

10. Restart your router

According to users, you might be able to fix the problem simply by restarting your router.

To do that, simply press the power button on your router to turn it off. If you want, you can disconnect all the cables from your router and leave it like that for a minute.

Now reconnect everything and press the power button to turn your router back on again. After doing that, wait while your router starts and check if the problem is resolved.

This is a simple solution, and several users reported that it works, so feel free to try it out. In some cases, users found that the router was the issue, so you might consider getting a new one.

11. Make sure that your browser is up to date

Sometimes the “Connection timed out” message can appear if your browser is out of date. Outdated software can have compatibility issues and bugs that can cause this and other errors to appear.

To fix the problem, be sure that your browser is up to date. To check for updates in your browser, do the following:

  1. Click on the Menu icon in the top right corner and choose Help > About Google Chrome.
  2. Your browser will now check for updates and install them automatically.

After you update the browser, check if the issue still persists. If the problem still appears, you might want to download and install a beta version of your browser.

Several users reported that installing Google Canary fixed the problem for them, so be sure to try that.

Alternatively, you can try a browser that we can’t recommend enough, browser that will make all the Chrome-induced aches just a thing of a past. We are, of course, referring to UR Browser, a privacy-oriented browser that makes the difference.
