Authentication Failed Error Code 403 Roblox

How do I fix “Authentication Failed Error Code: 403. An error was encountered during authentication. Please try again.”?

Experienced Issue
Whenever I try playing any Roblox game, the error code 403 authentication failed appears. And no signs of down or outages of Roblox.

Also here’s some of the screenshot!


Solutions that I’ve tried
I’ve looked at some information to fix it on DevForum Roblox, YouTube and Google, and I’ve tried them like resetting DNS, restarting the PC, removing the Roblox File and then reinstalling Roblox. But none of these works.

Issue Area: Engine
Issue Type: Connectivity
Operating System: Windows

I’m looking for any solutions. Any solutions will be appreciated!


Error 403 has been ocurring a lot to me as well. If you’re not using a vpn, try waiting some time. Usually waiting a bit helps as well. Error 403 means the server is denying you access.

What I did exactly to fix this is;

  • Log out of my account(s) and cleared my cookies
  • Uninstall Roblox
  • Change my ip through Private Internet Access VPN
  • Make a new account and try to join a Roblox game

If you follow exactly those steps I’m 100% sure it’ll work for you as well. If they don’t, you might have a hardware ID ban or some type of other more personal issue.


Can I use another VPN to change my IP? Because PIA (Private Internet Access) is paid.

Go to settings > WiFi > YourNetworkName properties > IP assignment > Manual

Go to CMD and run ipconfig /renew
