Firewall Blocking Internet [5 Easy Fixes]

What should you do if you are trying to view a web page in your Chrome browser and the message “No internet” appears despite the fact that your internet connection is active?

Isn’t it irritating when this happens?

This appears to be a problem with the Firewall configuration since it appears to be blocking Google Chrome from accessing the web page.

It’s because of the Firewall exceptions that have been established for Google Chrome, which might be owing to a program that has been installed lately, a recent update, or even because you unintentionally clicked on it.

This is a well-known problem, and it is also one that can be readily resolved.

Let’s have a look at how.

What is a Computer Firewall?

Connections are being denied by the Windows Firewall

The existence of a firewall or antivirus software on a local computer or network connection might have an impact on outgoing connections.

Windows includes a built-in Internet Firewall that is on by default and prevents any FTP traffic from passing through it.

You have the option of turning off this firewall (which Microsoft does not suggest) or configuring it to accept connections through CuteFTP.

Open ports 20 and 21 on your firewall by configuring it to do so (not blocked).

It may also be essential to provide CuteFTP special permission to access certain ports in order for it to function properly.


To add CuteFTP to the list of Windows Firewall exceptions, follow the procedures outlined below.

To add CuteFTP to the Windows Firewall exceptions list, follow the steps below.

1. In the Windows Control Panel, select Security Center, then Windows Firewall from the drop-down menu.

2. On the General tab, make sure that Windows Firewall is turned on, and then uncheck the box that says “Don’t accept exceptions.”

On the Exceptions tab, check the Programs and Services list to see if CuteFTP is among the programs and services mentioned. Look for the following:

CuteFTP (the interface) ftpte.exe (the file transfer protocol) (the Transfer Engine)

Both programs must be listed as exceptions in the exceptions list.

Follow the procedures outlined below to add either one or both programs to the list if they are not already there.

4. Select Add Program from the drop-down menu. The dialog window for adding a program appears.

5. Select CuteFTP from the Programs drop-down menu, then click OK. The dialog window for adding a program is closed.

6. Select Add Program from the drop-down menu. The dialog window for adding a program appears.

7. Click Browse to browse to the CuteFTP installation folder (which is by default located at C:Program FilesGlobalscape), then double-click ftpte.exe and then click Open.

8. To dismiss the Add a Program dialog box and save your changes, press the OK button.

Make that both applications are shown in the Programs and Services list, then click OK to close Windows Firewall.

The transfer engine and the interface will no longer be blocked by the firewall.

It’s true that cybercrime exists, and having an antivirus program is essential if you want to keep your data, privacy, and functioning safely on a regular basis.

Furthermore, modern antivirus solutions are almost always all-in-one packages that include cloud protection and firewalls, as well as system optimization and other features.

However, in some cases, the aforementioned firewalls might prohibit you from connecting to your Wi-Fi network, stopping you from accessing the Internet.

My antivirus software is preventing me from accessing the internet! Given the gravity of the situation, we felt it was important to address the issue in this post.

Consider taking a look at the actions outlined below to ensure that we can resolve this issue in a timely manner.

How can I unblock an Internet connection that has been restricted by my antivirus?

  • Start the Internet Connections troubleshooter and see if it helps.
  • Check the connection to make sure it’s working.
  • Examine the firewall’s exceptions
  • Restore the antivirus to its default configuration.
  • Reinstall the antivirus software.
  • Disable your antivirus software.

1. To begin, run the Internet Connections troubleshooter  

Settings may be accessed by selecting Start > Settings from the context menu.

2. From the drop-down option, choose Update & Security.

3. Now, from the left pane, select Troubleshoot, and from the right pane, pick Additional troubleshooters to begin the troubleshooting process.

4. Select Internet Connections from the drop-down menu and press the Run the troubleshooter button.

5. Follow the instructions on the screen in order to complete the operation.  

To begin troubleshooting in this circumstance, the specialized troubleshooter should be utilized. And, despite the fact that it may be deemed simple, it assisted a large number of customers in resolving their connection issues.

Checking the Connection

Let’s start by ruling out any other reasonable reasons for this occurrence.

There are numerous possible causes for your PC’s inability to connect to the Internet or your favorite Wi-Fi network.

As a result, we recommend that you follow the methods outlined below and investigate other possible causes of this burning issue:

1. Shut off your computer.

2. Reboot your modem and router.

3. See if anything changes if you use a LAN wire instead of Wi-Fi.

4. Enter Safe Mode with Networking enabled and attempt to connect.

5. Run the Windows Troubleshooter utility.

Your router/firmware modems should be updated.

Examine the firewall exceptions.

The antivirus or antimalware solution cannot, in and of itself, disable the internet connection.

However, by combining multiple security solutions into a single package, we were able to get third-party firewalls.

These firewalls might be preventing Internet or Wi-Fi access.

Sometimes by accident, and other times because you have a reasonable suspicion that your network is unsafe.

To control this, reconnect your router, reset all equipment as previously suggested, and monitor for changes.

If such steps are ineffective, be sure to properly check the Firewall component of your antimalware package.

Individual applications (such as browsers and e-mail clients) can be allowed to interact over the firewall by creating exceptions.

This method varies, so be careful to Google your antimalware or check the Help section to learn how to perform it.

Furthermore, several customers claimed that big upgrades created problems with various antivirus programs. Make careful you reinstall it, and perhaps the developers will release timely patches.

BONUS: Use a firewall to prevent unauthorized access to your Mac.

When you’re linked to the internet or a network, a firewall can protect your Mac from unwanted interaction made by other computers.

However, certain services and programs may still be accessed through the firewall on your Mac. As an example:

When you enable a sharing service, such as file sharing, macOS opens a particular port over which the service may interact.

Another system’s program or service can request and be granted access over the firewall, or it may have a trusted certificate and therefore be granted access.

You may choose applications and services and define whether they can access the firewall for further control.

Enable firewall protection.

1. On your Mac, go to the Apple menu > System Preferences, then Security & Privacy, and finally Firewall.

2. If the lock in the lower-left corner is locked, click it to unlock the preference pane.

3. Select Turn On Firewall from the drop-down menu.

Click Firewall Options and then perform any of the following to select extra security settings:

Allow just the following apps and services to connect: Click the Add button, then in the resulting box, pick the app or service.

Allow just the following apps and services to connect: Check the option that says “Block all inbound connections.”

Allow built-in software to receive incoming connections automatically: Check the box next to “Automatically enable built-in software to receive incoming connections.”

Allow downloaded signed applications to receive incoming connections automatically:

Check the option that says “Automatically enable downloaded signed applications to receive incoming connections.”

To make it more difficult for hackers and viruses to discover your Mac, enable stealth mode: Choose “Enable stealth mode.”

 OUR FINAL THOUGHTS

Most of the time, just blocking the executable file of the software is sufficient to prevent it from accessing the Internet.

This technique, on the other hand, may not be effective with online games.

Because Minecraft connects to the Internet through the Java application (executable file Javaw.exe), if you want to block access to Minecraft game servers, you should block the corresponding Java application (executable file Javaw.exe), which is why you should block the Java executable file Javaw.exe.
