If League of Legends shows "Firewall may be blocking your connection," try these steps: 1. Allow the game and patcher through Windows Firewall. 2. Temporarily disable third-party firewalls. 3. Reset Windows Firewall to defaults. 4. Manually create inbound/outbound rules for full access.

LOL Firewall May Be Blocking Your Connection [FIXED]

If you're encountering connection issues in League of Legends with the message "Firewall may be blocking your connection," the problem likely stems from network security settings restricting game traffic. Here's how to resolve it:

The operating environment of this tutorial: Dell XPS 15, Windows 11

1. Allow League of Legends Through Windows Defender Firewall

Configuring your firewall to trust the League of Legends application enables uninterrupted communication between the game client and Riot’s servers. This method adds both the game and its patcher to the firewall’s allowed apps list.

  • Open the Start menu and search for “Windows Security,” then launch the app.
  • Navigate to “Firewall & network protection” from the left sidebar.
  • Click “Allow an app through firewall” under the settings pane.
  • Select “Change settings” and scroll to locate League of Legends.exe and LoLPatcher.exe.
  • Ensure both entries have checkboxes marked for Private and Public networks.
  • If they are not listed, click “Allow another app,” browse to the installation folder (typically C:\Riot Games\League of Legends), and manually add both executables.

2. Temporarily Disable Third-Party Firewalls

Third-party antivirus or firewall software such as Norton, McAfee, or Bitdefender may enforce stricter rules than Windows Firewall. Temporarily disabling them helps determine if they are the source of the block.

  • Right-click the antivirus icon in the system tray (bottom-right corner of the taskbar).
  • Select “Disable,” “Turn Off,” or “Pause Protection” for a short duration (e.g., 15–30 minutes).
  • Launch League of Legends and check if the connection succeeds.
  • Important: Re-enable the firewall immediately after testing to maintain system security.

3. Reset Windows Firewall Settings to Default

If custom firewall rules have been corrupted or misconfigured, resetting the firewall to its default state can eliminate problematic entries while preserving essential protections.

  • Open Windows Security and go to “Firewall & network protection.”
  • Scroll down and select “Restore firewall defaults.”
  • Click “Restore defaults” in the confirmation window.
  • After the reset, re-add League of Legends and LoLPatcher to the allowed apps list using Method 1.

4. Manually Configure Outbound and Inbound Rules

Creating specific inbound and outbound rules gives granular control over how the firewall treats League of Legends traffic, ensuring all necessary ports and protocols are permitted.

  • In “Windows Security,” go to “Firewall & network protection,” then click “Advanced settings.”
  • In the new window, right-click “Inbound Rules” and choose “New Rule.”
  • Select “Program,” then “This program path,” and browse to LeagueOfLegends.exe.
  • Choose “Allow the connection,” assign it to all profiles (Domain, Private, Public), and name the rule “LoL Inbound.”
  • Repeat the process under “Outbound Rules,” following the same steps and naming it “LoL Outbound.”

How should I check if the computer suddenly fails to recognize the printer? How should I check if the computer suddenly fails to recognize the printer? Sep 20, 2025 am 08:27 AM

Answer: The computer cannot recognize the printer. It is usually caused by connection, drive, or service issues. First check whether the USB or network connection is normal to ensure that the printer is powered on; if the connection is correct, restart the device and check the driver status in the "Device Manager", update or reinstall the official website driver; confirm that the Windows "PrintSpooler" service has been started and set to automatic; use the system "Troubleshooting" tool to troubleshoot problems. If the driver fails to install repeatedly, you need to completely uninstall the old driver and clean up the residual files. After restarting, install the new version of the driver as an administrator, and use compatibility mode or system restore if necessary. If there is any problem after Windows update, you should first download the driver that is adapted to the new system, or roll back the update and check the service status. The details that are easily overlooked during the investigation include

How to limit download file sizes by Google Chrome How to limit download file sizes by Google Chrome Sep 09, 2025 pm 03:33 PM

Regarding the question of how Google Chrome limits the size of downloaded files, it should be clear that Google Chrome itself does not provide built-in functions that directly limit the size of file downloads. The main responsibility of the browser is to download files from the server according to user instructions, rather than manage or restrict the size of the downloaded files. Typically, such restrictions are more often implemented on the server side, at the network level (such as router settings or network security devices), or through dedicated download management software.
