Individual application cannot access Internet

An individual Internet application (such as Amazon Fire TV, browser games, Netflix, antivirus software) cannot access the Internet, although other applications on the same device can access the Internet at the time the error occurs. The application may display one of the following error messages:

  • Server is not responding
  • Server not found.
  • Failed to connect to server
  • Online update has failed
  • Network error when downloading updates

1 Adjusting filters for web pages

When the filter for web pages is enabled in the FRITZ!Box parental controls, direct IP access to websites is blocked as a rule. This means that an application that uses direct IP access cannot access the Internet until you permit access to the IP addresses being blocked by the FRITZ!Box:

Example:
A virus scanner cannot find any updates when it searches for them at the IP address 212.42.244.80 instead of at the corresponding domain name www.updateserver-of-virus-scanner-manufacturer.com.

Preparations

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Filters" in the "Internet" menu.
  3. Click on the "Lists" tab.
  4. Click on the "Edit" link next to the list "Permitted IP addresses".
  5. Click on the link "Delete all non-allowed IP addresses from the list".
  6. Confirm the question "Do you really want to delete all non-allowed IP addresses from the list?" with "OK".
  7. Click "OK" to save the list.

Reproducing the issue

  • Reproduce the issue by starting the respective Internet application and then attempting to access the Internet with it.

    Example:
    Restart the computer when the virus scanner automatically searches for updates when Windows starts.

Allowing access to blocked IP addresses

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Filters" in the "Internet" menu.
  3. Click on the "Lists" tab.
  4. Click on the "Edit" link next to the list "Permitted IP addresses".
  5. Allow access to IP addresses accessed directly by the Internet application.
  6. Click "OK" to save the list.

2 Disabling filters for web pages

If the FRITZ!Box parental controls are configured incorrectly, individual applications may not be able to access the Internet. Therefore, disable the filter for web pages in the FRITZ!Box for testing purposes:

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Filters" in the "Internet" menu.
  3. Select the access profile "Unrestricted" for the respective network device or Windows user from the drop-down list.
  4. Click "Apply" to save your settings.

If the application is now able to access the Internet, then the filter for web pages in the parental controls was blocking it. You can either choose to not restrict Internet access for the respective device, or you can adjust the filter for web pages in the FRITZ!Box parental controls.

3 Setting up port sharing in the FRITZ!Box

By default, the FRITZ!Box's firewall protects all of the devices in the home network from incoming connections and unsolicited data from the Internet. However, in order to use certain online games (for example Call of Duty) and individual chat applications, other users from the Internet must be able to access your computers and game consoles.

The following steps are only necessary if you are experiencing problems with joining online games or chats:

  • Set up the FRITZ!Box for automatic port sharing with UPnP,
    • or:
  • Configure static port sharing in the FRITZ!Box for the ports and IP protocols used by the application.

    Note:You can find information on the ports and IP protocols that are used in the manual, or consult the manufacturer of the application directly.

4 Configuring the firewall

A firewall on the device may be preventing individual applications from accessing the Internet:

  • Configure the firewall on the device so that the Internet application in question has unrestricted access to the Internet:

    Note:You can find information on configuring the firewall in its manual, or consult its manufacturer directly.
