How to fix connection failure error in LOL PBE, DTCL PBE

This connection error can be caused by many different reasons, PBE servers are often used for testing so they may experience unannounced maintenance errors due to unexpected incidents. Or simply the number of people accessing the PBE server is too large, causing congestion and inability to connect.

Another reason is that the network connection is unstable, leading to the inability to connect to the server, causing the connection to fail. Maybe you are using a VPN or Proxy that is not compatible with the Riot Games server. Or the default DNS of the network provider is having an error, making it impossible for gamers to access the server. In this case, you should turn off the VPN or use another Proxy, change the DNS and try again.

Other causes include firewalls blocking the connection between the game client and Riot servers, or your modem/router. Some antivirus software may mistake LeagueClient.exe for malicious software and automatically block it. You can try disabling your firewall and try connecting to the PBE server again.

In addition, when updating the PBE version, the update process may be missing files or corrupted files. After trying a few errors without fixing them, you can delete the entire LOL PBE and reinstall it.
