Why does ROBLOX Show Error Code 403? How to Fix?

If you are receiving Error Code 403 in ROBLOX, it means that you do not have permission to play that game. This is an authentication error, and it occurs when trying to launch the game.

Some games are purposely locked by developers, which is why you might be unable to access the game. However, this error can also occur if there is corruption in ROBLOX cache data or if the default DNS is not working properly with Roblox.

Before you start applying the following methods, we recommend that you restart your computer and router. Sometimes a simple restart fixes connection and authentication errors.

1. Log out and log in.

Your login cookies may become corrupted; hence, Roblox is not allowing you to enter the game. Cookies are small pieces of text that can be used by a website or application to remember the user’s information. Cookies are created by the application or website when you sign up or log in. Every time you log in, the new cookies will be sent to your browser by the website with the help of your login credentials.

If you have been playing this game for a long time and are receiving this error message, try logging out and then logging back into your Roblox application or website. In this way, you will be able to create new login cookies, which might fix the error. To do so, 

Open the Roblox Player and log out from there. Once you have logged out, open it and log in. Then, try entering the game that shows you the error code 403.

2. Delete the Roblox cache folder.

The Roblox cache folder contains data that the application requires and that the user frequently accesses, such as log files, local storage, cookies, and cache files of images, saved games, etc. Thus, the application won’t need to request data from the server, which takes time and can result in a poor User Experience (UX). Therefore, cache files store data that the user wants or accesses frequently.

So, if there is corruption in the Roblox cache folder, it won’t work properly, which can result in this error message. Therefore, try clearing the Roblox cache folder. This action will recreate the cache folder when you launch Roblox again. To do so, follow these steps:

1. Hold the Win key and press the R key to open the Run window.
2. Enter ‘appdata‘ in the search box and click ‘OK‘ to navigate.
   
3. From here, go to the Local folder and find the Roblox folder.
   
4. Hold the Shift key and right-click on the Roblox folder.
5. Select Delete to remove the folder.
   
6. Once the folder has been removed, launch the Roblox player and try to play the game to determine if the error has been fixed or not.

3. Try the Roblox Microsoft Store version.

Roblox error code 403 can also occur when players commit mistakes such as harassment or promoting toxicity. One user confirmed that whenever he received this error on the browser, he had to use the Microsoft Store Roblox version with a new account to avoid the error.

You cannot encounter Roblox error code 403 after getting banned because it is not a hardware IP ban. Instead, you can consider it more like a browser ban, as users can access the game by simply creating a new Roblox account and using the Microsoft Store version. This indicates that it is not a permanent ban or IP ban.

Now, if you are thinking of creating a new account and logging in through the same browser to fix this error, unfortunately, you are mistaken. You will have to create an account and log in to the Roblox application, which should be installed through the Microsoft Store. In this way, you will be able to avoid the error message and play the game. Follow the instructions:

1. Click the Start Menu and type “Microsoft Store.
   
2. Open the Microsoft Store and search for Roblox.
3. Click on “Roblox” from the results.
4. Now click the ‘Get‘ button to download and install Roblox.
   
5. Once it is installed, click the Play button to launch Roblox.
6. Then, click the ‘Signup‘ button and create a new account.
7. Once completed, log in to that account and attempt to play the game in which you were receiving the error message.

4. Use Google DNS.

If your default DNS is not stable, you may receive this error message, as slow DNS reduces overall internet performance, which can lead to this error.

DNS, or Domain Name System, is used to convert human-readable names into IP addresses so that the browser can understand the address and communicate with the server to fetch the requested data. Hence, if your DNS is slow, it will result in slow performance, which may lead to this error. Therefore, try changing the default DNS to the Google DNS server, which is often faster, more reliable, and more secure than the default DNS server. To integrate Google DNS, follow these steps:

1. Press the Windows key and type Control Panel.
   
2. Open the control panel, and go to Network and Internet > Network and Sharing Center .
3. Click Change adapter settings from the left sidebar.
   
4. Here, you will see all the network adapters. Right-click on your network adapter and go to its Properties.
   
5. Here select the Internet Protocol Version 4 (TCP/IPv4) and click Properties.
   
6. Now, select ‘Use the following DNS server addresses‘ and type the following DNS addresses.
   An alternative DNS server is 8.8.4.4.
7. Once completed, click OK to save the changes.
   
8. Now, go to Roblox.com, try to play the game, and see if the error is resolved or not.

5. Allow Roblox through Windows Firewall settings.

If you are still encountering the error message, you need to ensure that Roblox is allowed in the firewall settings. The Windows firewall monitors incoming and outgoing data to protect the computer from unauthorized access.

There is a small possibility that the Windows firewall is not allowing Roblox to communicate with the game server. Hence, try allowing Roblox and check whether the error is fixed or not.

1. To do so, press the Windows key, type “Control Panel,” and open it.
   
2. Now, go to System and Security > Windows Defender Firewall.
   
3. Then, click “Allow an app or feature through Windows Defender Firewall” from the left sidebar.
   
4. Click ‘Change Settings‘ and find ‘Roblox‘ under ‘Allowed Apps and Features.’
5. If you can find it, tick the boxes under Private and Public for Roblox. Otherwise, add Roblox using the “Allow another app” option. Then, tick the Private and Public boxes for Roblox.
   
6. Once done, click OK to close the window.
7. Then, launch Roblox and check if the error persists. If the error continues, try disabling the Windows firewall temporarily.

6. Appeal for a Ban.

If error code 43 persists even after attempting all the solutions, you should contact the Roblox appeal team and briefly describe the problem. However, this method will only work if you have not violated Roblox Community Standards.

1. Go to Roblox support and log in with your credentials.
2. Once you are logged in, provide the contact information and select the device that you used to play Roblox games.
3. Choose “Moderation,” then select “Appeal Account.
4. Now, briefly describe your issue and click Submit.
   
5. Now, just wait for the response at your provided email address.
