How to Fix League of Legends Error code 0U Issue

Want to know how to fix League of Legends Error code 0U. League of Legends can be hard to stick with sometimes, and it gets harder when error codes like “0U” show up. The League of Legends error number 0U means that the PBE client isn’t loading, which means that the game‘s PC installation can’t find new features and upgrades. Some people who use the PBE app to play League of Legends are getting an error code 0U.

Because of the error, the client won’t show the right home screen, summoner icon, or any of the client tabs. Players have said that this mistake caused their PBE clients to show a black screen. When players on the League of Linux subreddit ran into this problem, they contacted Riot Support, who told them to run the Hextech Repair Tool. Though there are other methods you can try to Fix League of Legends Error code 0U.

It can be hard to get into a League of Legends game sometimes. League has a separate client screen that lets players talk to their friends without actually starting the game. This is different from other games where the lobby is part of the game itself. Visit their official site for more fixes.

How to Fix League of Legends Error code 0U

Allow League of Legends through the Firewall

  • Press the Windows key, type “Firewall” into the search box, and choose “Open.”
  • Click on Firewall > Allow an app through.
  • If League of Legends isn’t on the list, click Change Settings and then click Allow another app.
  • Click the “Browse” button, find your game, and then click “Add.”

Check For Regular Updates On The Game

You should always check for game changes, not just if some of your files are broken. Sometimes, a new fix comes out, but you either don’t get a message about it or you don’t get a message at all.

This will stop the game from updating to the latest version, so bugs that were fixed in the new version will come back and ruin your fun. Set the updates to run automatically so you don’t forget.

Check For Damage In The Game Files

When you download a video game, your computer gets a lot of files that talk to the server. This is how the game keeps track of your progress and how you like to play. But you won’t be able to start the game if these files are broken. How can you tell if the files for the game are broken? You will have to run a repair test on the computer to find out if any files are broken.

Delete The Game Files And Reinstall

Adding on to the last point, if you can’t fix the problem by finding the broken game files, you’ll have to delete them. When you delete the game from the server, the files that are broken are also deleted.

After this, you can restart the game with a new version that doesn’t have any problems. You can also try to find a new update for the game before you delete it. Very rarely, this will also fix the computer’s broken game files.


Can you merge two LoL accounts?

If you have more than one account, go to My Account > Settings > Merge to combine them. This is helpful, for example, if you play in more than one league and want to reach them all from the same place.

Did League remove the repair button?

We took the self-repair button off the League of Legends client settings page because it didn’t do anything useful. The Riot Games client settings page is still the way to get to self-repair for clients.
