What is Roblox Error Code 403? Common Steps to Fix It

Roblox is a game that needs no introductions. Almost 70 million people play the game every day. Being popular doesn’t mean that the game doesn’t have its fair share of issues. One of the most common issues with Roblox is the 403 error code. 

Fortunately, there are ways to fix Roblox error code 403. If you’re tired of troubleshooting the 403 error code, then this guide is for you. 

What is Roblox Error Code 403?

With time, Roblox is getting more and more error-prone. The error code 403 is one of the most common ones in Roblox. You’ll encounter the error code after you click on the “Play” button.

When the error code comes up on your screen, it’s accompanied by a note saying “An error was encountered during authentication. Please try again.”. This error means that you don’t have the permission to access the game. 

There can be several reasons you’re getting the Roblox error code 403. The most common reasons are:

  • The Roblox server is under maintenance or facing downtime.
  • You’re using a VPN connection.
  • There’s corruption in the Roblox cache folder.
  • Your current DNS server isn’t stable.

Now that you know about the common reasons you’re getting Roblox 403 error code, let’s go over the ways to fix the issue. 

Easy Ways to Fix Roblox 403 Error Code

There are several steps you can take to fix the Roblox 403 error code. Let’s go over them one by one.

  1. Check the Roblox Server Status

The first thing that you need to do when you get the Roblox error code 403 is check the Roblox server status page. Roblox is a multiplayer game; so the servers go under maintenance now and then. 

Whenever Roblox servers are under maintenance or facing downtime, you’ll come across several error codes. Checking the server status page can be your first step whenever you encounter a Roblox error code. 

The only thing you can do in this situation is to wait until the servers become operational again. 

  1. Clear the Roblox Cache Folder

Similar to EVERY APPLICATION EVER, Roblox stores cache data, allowing it to access the Internet faster. But sometimes, sudden system crashes or malware attacks can corrupt the cache folder. Issues with the cache folder can cause the Roblox 403 error code. 

The solution in this situation is to clear the cache folder. When you delete the cache folder, it won’t affect the app’s performance or user data. 

Here’s how to clear the Roblox cache folder:

  • Press the Win + X hotkeys to open the Power Menu.
  • Choose the Run option from the list of menus. Or, you can just press Win + R to open the Run dialog box.
  • In the search bar, type %localappdata% and click on OK. It’ll open the Local folder, which contains the cache folder of all installed applications.
  • Search and open the Roblox folder.
  • Press CTRL + A to select everything & then press Shift + Delete to delete everything permanently.

Restart your device to see if you’ve gotten rid of the Roblox error code.

  1. Disable VPN Connection

Roblox may not work perfectly if you’re connected to a VPN. VPNs can slow down your internet connection, which may cause apps and websites to open slower.

An active VPN connection can be the major reason why you’re getting the Roblox 403 error code. If you’re connected to a VPN connection, disconnect and try playing the game again. 

Open your VPN app and hit on “Disconnect”.

Each VPN application will have different steps on how to disconnect the connection. There’s usually a visible button or option to click in the main window to turn off the VPN.

  1. Do a SFC and DISM Scan

If there’s a corruption in Window’s file, then you may also get the Roblox 403 error code. If that’s the case, you can run an SFC (System File Checker) scan, a Windows built-in tool that scans your system for missing or corrupted files. The tool also replaces the file automatically if it’s needed. 

You can run an SFC scan by following the below steps:

  • Open the start menu on your device by pressing the Win key.
  • In the search bar, type Command Prompt and then click Run as administrator from the right pane.
  • If UAC pops up, click on Yes.
  • Type this command in the command prompt and press enter – sfc/scannow
  • Wait until the scan is complete, this may take a while. 

Restart your device and check whether the issue persists. Suppose the Roblox error code 403 comes up again. In that case, you’ll have to run the Deployment Image Servicing and Management command line tool to restore the system files and repair any corrupt system images.

Here are the steps on how to do it:

  • Run the command prompt as an administrator.
  • Type the following command and press Enter – DISM /Online /Cleanup-Image /ScanHealth
    Dism.exe /online /cleanup-image /restorehealth
  • After the scan is complete, check if the error code comes up again.
  1. Allow Roblox on Firewall

It’s not uncommon for online games to stop working or throw an error code because of an interruption from the Windows  Firewall. 

To fix this issue, you’ll have to allow Roblox to run through the Windows Firewall. Once you allow the app to run through the Firewall, restart your computer to see if the issue persists. 

  1. Switch to Google DNS

Your ISP will have its own DNS server, but it’s usually unstable and can cause trouble opening up a lot of apps and websites.

While there are several great DNS service providers for added safety, Google DNS is the best option for all. Here are the steps to switch to Google DNS:

  • Open the Power Menu, and then choose Network Connections from the menu list.
  • Go to Advanced Network Settings.
  • Expand the WiFi tab and click the Edit button next to More adapter options. 
  • Highlight the option titled Internet Protocol Version 4 (TCP/IPv4) and click on the Properties button.
  • Click on the Use the following IP addresses button.
  • Type in the Preferred DNS server box and in the Alternate DNS Server box.
  • Click on OK to save the settings. 
  • Highlight the IPV6 and click on Properties.
  • Type 2001:4860:4860::8888 in the Preferred DNS server box and 2001:4860:4860::8844 in the Alternate DNS server box.
  • Click OK to save the IPv6 DNS settings.
  1. Reinstall Roblox

If you’ve tried all the above methods and you’re still getting the Roblox error code 403, it may be time for you to reinstall Roblox. 

Uninstall Roblox from your device and then install it again. This will remove all the corrupt files and documents in the source and most probably fix the issue.
