Fix Roblox Error Code 523 [100% Working] – When trying to launch a Roblox game, users may encounter error code 523. In many cases, it prevents you from connecting through a private server hosted by another player, but it can also occur for other reasons.
Fix Roblox Error Code 523
If the local client is unable to establish a connection with the remote Roblox server due to error 523, then there are problems with the Internet on its part, or something in the system is preventing this connection. The reasons for blocking access to the game may be as follows:
- Unstable internet connection.
- Establishing a connection to the game server is being blocked by Windows Firewall or a third-party firewall.
- The browser has an extension that blocks ads, such as Adblock and others.
- Not having access to the beta version of the game can also result in this error code.
Restart your computer before applying the solutions. Sometimes this is enough to get rid of error 523.
Checking Roblox Server Status
Similar error codes are associated with the back end. The Roblox game servers may be down or under maintenance. Therefore, first of all, you need to check their condition. Enter the query “Roblox server status” in the search engine and in the search results go to, for example, the Downdetector service.
If problems are found on the server, wait a while until they are fixed.
Checking your internet connection
If error 523 occurs, also restart the router. There may have been an error while loading it. Therefore, to clear the erroneous network configuration, unplug the router from the network, then wait 10-15 seconds before plugging it back in.
Please note that it is preferable to use a cable connection (Ethernet) for gaming, as Wi-Fi interference and the connection of other mobile devices can significantly reduce the speed of the wireless connection.
Allow Roblox Through Firewall
Windows Firewall is designed to protect user data, including monitoring incoming and outgoing traffic based on security rules. But sometimes it can prevent connection to external game servers. In this case, you need to allow communication with Roblox in the firewall by following these steps:
Open the Control Panel window with the control command launched from the Run window (Win + R).
In the top right menu, switch the view to large/small icons and go to the “Windows Defender Firewall” section.
In the left pane, click the Allow an app or feature to interact with Windows Defender Firewall tab.
To open access to editing permissions, click on the “Change settings” button. Find Roblox in the list and check the boxes for private and public networks.
If it is not listed, click “Allow another application” and specify the location of the Roblox executable file, by default it is located in the C: / Program Files folder. Then apply the settings and restart your computer.
Removing an ad blocker
The AdBlock extension and other ad blockers are designed to block ad blocks on websites, but can also result in error code 523 when running Roblox in a browser. To disable, follow the steps below.
Expand the main menu in the Chrome browser by clicking on the three dots in the upper right corner and go to the menu More tools – Extensions.
Disable ad blocking extensions by moving the switch to the off position.
Reset browser settings
Error 523 may be caused by corrupted browser components. Try to return it to its original state.
Open the menu again by clicking on the three dots and go to “Settings”.
In the panel on the left, click on the “Reset and Remove Malware” tab.
Then click on “Restore default settings” and reset.
Deleting log files
Log files store game configuration data. Cleaning them helps to eliminate errors related to the server side and authentication.
Open the Run window by pressing the Win + R keys, enter appdata and click OK. The explorer opens with the contents of the AppData directory.
Go to the Local folder and find the Roblox subdirectory in its contents. Then open the Logs folder and delete all files.
Then open the game and see if it is blocked from launching by error 523.
Reinstalling the game
If the above methods did not work, the game components may be corrupted. Try to fix error code 523 by reinstalling Roblox.
Go to “Programs and Features” by command appwiz.cpl from the Win + R window. In the list of programs, find the Roblox game, right-click on it and delete it. After uninstalling, download the game from the official site and run the installation. Check if error code 523 is fixed when launching Roblox.
