As a platform for hosting various user-made games, Roblox has one of the fastest-growing gaming communities on the internet.
Considering its massive numbers, it’s no surprise that some users might occasionally encounter server errors that stop them from playing their favorite games. This ONE Esports guide will teach you how to fix error code 403.
According to 2024 statistics at the time of writing, the platform is home to about 70 million active users per day, with more than four billion accounts created since its inception in September 2006.

If you’re reading this article right now, there’s a chance that you are a part of those being annoyed by this particular error.
But don’t worry, we got your back! Here is everything you need to know about how to fix error code 403.
What is Roblox error code 403?

Error code 403 is an example of a common error that appears right after entering a server. It is similar to other known errors, such as error code 529.
Once triggered, this error will show itself as a text saying, “An error was encountered during authentication. Please try again.”
Some possible causes of this error code include the following:
- Logging in using a secondary account in Roblox via browser while your first account is logged in on your Roblox app. If your app is running in the background, you will likely get the error code 403.
- Using a Virtual Private Network or VPN. The platform bans some IP addresses to prevent players from abusing its games. VPN changes your actual IP address, which might get flagged by the system.
- Your PC’s firewall or antivirus prevents the platform from working properly. Firewalls and antiviruses have a habit of blocking apps that are not included on their allowed list.
- You have issues with your internet connection. The platform only requires at least four to eight MB/s of internet speed. However, if your internet is unstable enough, it might also give you the error code 403.
- The platform is currently down, probably due to maintenance. If this is the case, the problem is not on your end anymore, since other players will get the same error as well if the servers are down.
How to fix error code 403 in Roblox — suggested methods
Log out of the Roblox app

Open your Player app and click the circle with three dots on the left side of your screen.
You should see a set of options like the marketplace, premium, and profile. Look at the bottom of the list and click “Log Out”.
You may now play Roblox on your web browser using a different account without encountering the error.
You can also open your Task Manager (Press Ctrl + Shift + Esc for Windows 11 users), find the app in the background processes, then right-click and select “End”.
Turning off your VPN

You may skip this method if you’re not using a VPN. Go to your device’s settings and head over to the options under “Network & Internet”. Select VPN and turn it off by editing the proxy server.
Try opening your Roblox Player again and see if it fixes the issue.
Adding Roblox to Window’s firewall list of allowed apps

Type “firewall” on your taskbar’s search box to open the menu for “Firewall & Network Protection”. Click “Allow an app through firewall”, and select “Change Settings”.
Look for the Roblox app in the list and check its boxes under Private and Public.
If it’s not on the list, use the “allow another app” option to add Roblox in the Firewall settings.
Tweaking your antivirus settings

Turning off your antivirus while playing Roblox is an easy way to fix error code 403, but it would be better to set your antivirus in a way that it recognizes it as an excluded app.
The methods for doing this might vary based on the antivirus you’re using. But for those who rely on Windows Security:
- Go to virus and threat protection settings
- Scroll down to “Exclusions”
- Click “Add or remove exclusions”
- Look for File, then add the Roblox app from its file location
Deleting Roblox folder on AppData
Open the Run App and type “%appdata%.” A window should open and on the top click Appdata.

In the Appdata folder, open the Local folder, find the Roblox folder inside, and hit delete.
Restarting your router or modem
If your internet connection is unstable, consider restarting your router or modem before opening Roblox and rejoining a game’s server.
You can also do other things that improve your internet signal by changing your router’s position or subscribing to a better plan.
Checking Roblox’s status

To find out if the platform is undergoing maintenance, visit status.roblox.com and ensure that all of its servers are operational.
If the site implies that it’s undergoing maintenance or is experiencing a problem with something, try entering at a different time.
Reporting the Problem to the Roblox Support Team

If all the methods above fail, your last choice is to send a message to the official support team.
They can respond to user queries involving technical issues. You can contact the Roblox Support Team here.
