How to Fix Error 523 on Roblox

Keep seeing an error 523 on Roblox?

Roblox is a free-to-play platform where you can join various user-created games and worlds. You can also create your own map or build different obstacles and challenges to have your friends over for some fun. 

Although Roblox is a stable platform, it’s not flawless, and you can encounter issues, especially when joining user-created games. 

One of the most common problems on Roblox is the error code 523. This issue on the platform occurs when you try to join a server or game from other users. Instead of loading the world, an error code will stop you, and you’ll be stuck in the game library with nothing to play. 

Based on what we know, this issue is mainly caused by improper server configuration. The game creator or world may have set its privacy to private, preventing other users from joining. 

However, it can also be due to network-related issues, corrupted files, or faulty Roblox servers. 

Given the number of possible causes for the error code 523 on Roblox, troubleshooting can be confusing. 

Lucky for you, we got you covered. 

Today, we will show you what to do if you see the error code 523 on Roblox. 

Let’s get started!

1. Check Roblox Servers. 

If you can’t join a game on Roblox, the servers could be offline due to unexpected errors or maintenance. To confirm this, you can use third-party tools like Downdetector to view the current status of Roblox’s servers.

Since server-related issues can’t be addressed on your end, the only thing you can do if the servers are down is waiting for Roblox’s team to get things in order on their end. 

On the other hand, you can proceed to the following method below if there’s nothing wrong with the servers. 

2. Restart Your Computer. 

Before changing anything on your account or system, we recommend restarting your computer first if you can’t join a game on Roblox. This will allow your system to reload its resources and eliminate any errors that may have occurred during use. 

You can follow the guide below to restart Windows: 

  1. First, access the Start Menu on your computer. 
  2. After that, go to the Power Options tab. 
  3. Lastly, click on Restart to reboot your system. 
Restart your PC

Once done, go back to Roblox to check if the problem is solved. 

3. Check the Game Privacy. 

Another reason why the error 523 error code occurs on Roblox is if you’re trying to join a private server. If you know the owner of that server, ask them to check their privacy settings and ensure that it’s not set to ‘Private’. 

Try joining the game after the owner changes its privacy to see if the problem is solved. On the other hand, try finding another game if you don’t know the server’s owner. 

4. Clear Your Log Files. 

Roblox generates cache and log files to keep preloaded resources from the web. This allows the game to load the map and world faster on your computer. If you can’t join a game that you usually play, try clearing your log files. 

Follow the steps below to guide you on the process: 

  1. First, open the Run Command by pressing the Windows + R keys on your keyboard. 
  2. After that, type ‘%localappdata%’ and hit Enter to open the folder. 
  3. Now, open the Roblox folder and click on Logs
  4. Lastly, delete all the files inside the folder.

Try playing another game on Roblox after clearing your log files to check if the problem is solved. 

5. Allow Roblox Through Your Firewall. 

Windows Firewall is a security feature available for Windows operating systems, which controls the access of applications to the internet. If you see the error code 523 on Roblox, your firewall could be preventing it from connecting to the servers. 

To fix this, ensure that Roblox is allowed to access your public and private networks: 

  1. On your computer, go to Windows Settings and click on Update & Security
  2. After that, click on Windows Security on the side drawer. 
  3. Now, go to Firewall & Network Protection and click on Allow an App Through Firewall.
  4. Finally, locate Roblox from the list and ensure that it’s allowed to access your network.

Once done, go back to Roblox’s website, launch another game, and see if the error code still occurs.

Here’s what you need to do to delete Roblox:

  1. First, open the Control Panel on your computer. 
  2. Next, click on Uninstall a Program and look for Roblox
