Firewalls are a great tool when protecting your computer, but sometimes they can interfere with the way your PC communicates with the Rocket league servers. To determine if your Firewall is the culprit try disabling it temporarily and launching Rocket League.
To disable the Windows Firewall:
- Press the Windows key
- Type Windows Firewall in the search bar
- Select Turn Windows Firewall on or off
- Select both the Turn off Windows Firewall options are selected
- Select OK
Note: Exercise caution when using your computer without Firewall protection. Once you are finished diagnosing your connection problems it is recommended that you turn your Firewall back on.
