Hello everyone, friends who love League of Legends! The new season of S11 is menacing, and PBE has become a blessed place for us to experience new ways to play in advance. However, some friends encounter various problems when logging in, such as not being able to log in, not being able to log in, not being able to open, and even the embarrassment of not being able to update. Don't worry, I've compiled a "Unlock Login Password" tip for you to swim in the battlefield of PBE!

2.The Firewall has become a "spoiler"? Close it!
Oops, the firewall has become your "little assistant" for logging in? You're welcome, turn it off! The firewall may make your login road bumpy, so turn it off and make it smooth sailing.
3.Is the file path in Chinese? It's English!
Friends, is the file path hiding a "Chinese bomb"? Click on the Riot client desktop shortcut, find "Open file location", see if the path is in Chinese, don't forget to change to English. After speeding up, reopen the client, and the login problem disappears.
Uh-huh, the above is the magic trick to solve the problem that the pbe Meitest service fist client can't be opened! Stop worrying about login issues and enjoy the new season's battles!
