The error flashes a message as well that reads “An error was encountered during authentication. Please try again”
Unless the authentication is not done, you’ll not be able to play the game.
You can encounter Roblox Error Code 403 error at the time of login and this happens mainly if there is a Roblox server outage, your PC defender is blocking the access, the internet connection is not stable or a bad VPN server is slowing down the internet connection which eventually causing this issue.
How to fix Roblox Error Code 403

Only when the server is up and running fine, we will try these methods.
There are several means you can check if the Roblox server is working fine.
They have a server status page that you can check out to see if there is any service outage.
1- Is Roblox Down? Check the Server Status page
Is Roblox down?
Go to the Roblox Server Status page if all the services are operational. If all of them are operational, you are good to go.

At the bottom of this page, you can check the status history as well.
Check Roblox Twitter
The other way is to check Roblox’s Twitter Handle if there is any update regarding the server outage.
If you like you can follow the Twitter handle so that you get a notification whenever they tweet about server outages or any other problem.
Check Third-party Tool
There are plenty of good websites that keep track of the server status of top services. for example, Down Detector.
Go to Down Detector and enter “Roblox” You will have a chart showing the server status.

This website shows if there is any outage in the last 24 hours.
However, from the history, you can check the status over a long period of time.
2- Unstable Wi-Fi
Needless to say that since this is an online gaming platform, the internet should work perfectly if you want an uninterrupted gaming experience.
An unstable internet connection can cause various problems.
With a faulty internet, you can not go through the authentication process while logging into your Roblox account and hence throws “Roblox Error Code 403. An error was encountered during authentication. Please try again”
So make sure your Wi-Fi is stable, and fast, and offers you uninterrupted service.
Go to the browser and open your favorite website to check the Wi-Fi connection. Also, you can test the internet speed using speedtest.net.
Go to Youtube and play any random video if that plays well.
If it buffers too much, your Wi-Fi is not working fine and you need to fix it first.
3- Disable VPN
While VPN could be very useful to access websites or services which are not available in your region, it is also known to create several problems.
In many cases, VPN slows down the internet speed which interrupts various online services.
So I always advise buying a good VPN service such as ExpressVPN or Nord VPN if they really want to use VPN and disable it on your device when they are not required as it is very easy to switch on/off VPN service.
Disabling VPN can not only fix Roblox Error Code 403, but it can also be helpful in fixing other problems as well such as errors in body stream in ChatGPT, Zoom Error Code 10004, etc.

Disable VPN and check if it fixes the Roblox error.
- Go to Settings by clicking the Windows icon from the left-hand side menu.
- Then go to, “Network and Internet“
- Then select “VPN” and disable it if you have any active VPN.
If you are using a VPN service through a client that you’ve downloaded, you can disable it by opening the client.
Generally, a shortcut from the desktop or at the taskbar is created after the installation.
However, some VPNs use browser extensions to provide the services.
If that is the case, it can be disabled by going to the extensions installed on your browser.
