1. Check Internet Stability

When you see “an error was encountered during authentication” on Roblox, it doesn’t necessarily mean you’re banned. It can also happen if Roblox has trouble verifying you due to an unstable or slow internet connection. You should check your internet speed in this case.

Restart your modem and router: Restarting your modem or router once in a while will refresh your connection and clear any temporary problems, ensuring stable internet speeds. We suggest restarting your modem at least twice a week.

Update your internet plan: Games like Roblox need a strong internet connection. If you have a slow connection, upgrade to a better plan.

Change ISP: If upgrading the plan doesn’t improve your internet speeds, it’s best to change your ISP.

Reset network settings: If your Wi-Fi is working properly but you’re still having issues, it could be due to problems with your device. You can reset the network settings on your iPhone, Android, or PC to see if that resolves the problem.

2. Change DNS on Windows

Even with a good ISP, you may encounter Roblox Error Code 403 due to internet stability. Try changing to a different popular DNS to see if the problem persists. We have a guide on how to change DNS on Windows. Follow it and let us know the outcome.

4. Disable VPN

Using a VPN while playing Roblox may result in error code 403 if you are banned, as it is considered cheating. Additionally, VPNs can slow down internet speeds, which can prevent Roblox from verifying your account. Therefore, disable the VPN and see if you still encounter the error message in Roblox.
