Getting This Error Code When Launching The Game

Greetings to all, I downloaded the game ‘League of Legends’ on my PC yesterday. But I am having a problem when I am trying to launch the game. I am exactly getting this error message “Something’s up with our servers and it’s preventing you from patching. We’re giving it another shot. In the meantime, you can check the status of our servers here. (Error code 003).” I have no idea what could be the issue. Has anyone else come across this issue before? Please help

I was trying to solve the issue myself by updating the GPU driver if it can solve the issue. But nothing happens. Then I searched online and found this guide. They suggested some important solutions there. First I run the hextech repair tool and disabled the Windows defender firewall. The problem was solved after doing the methods perfectly. I no longer receive such error messages when I launch the game, and I enjoy playing it now.
