How to Fix Roblox Error 403

Quick Fix

  • Press *Windows + R* keys and type %appdata% first and again *Windows + R* with %localappdata% inside the windows that open.
  • Look for the *Roblox* folder inside both of the File Explorer windows that opened, click it and press *Delete*. If only one of the windows features the Roblox folder that is fine.
  • Reinstall the game after this and it should work fine.

Another thing is that Roblox doesn’t like overlays on your screen so if you have the RivaTuner from MSI Afterburner overclocking utility running, try to turn it off and close the window to see if Roblox continues to throw the 403 error.

1. If You Play Inside a Browser First Clear Your Cache and Cookies

Firefox: Options –> Privacy and Security –> Cookies and Site Data –> Clear Data

Safari: Preferences –> Privacy –> Manage Website Data –> Remove All

Edge: Settings > Privacy, search, and services > Clear browsing data > Choose what to clear

2. Disable Browser Extensions

Chrome: Menu –> More tools –> Extensions

Firefox: Menu –> Add-ons and themes

Safari: Preferences –> Extensions

Edge: Settings –> Extensions

Disable all extensions and re enable one by one to identify any problematic ones.

3. Check Your Internet Connection

  • Run a speed test (on speedtest.net)
  • Restart your router and modem
  • Try connecting with a wired Ethernet cable if you’re on WiFi

4. Check Your Account Status

  • Log in to Roblox.com
  • Look for account restriction notices
  • Review recent activity for suspicious logins

5. Correct System Time

Windows: Settings –> Time and Language –> Date and time

macOS: System Preferences –> Date and Time –> Enable *Set time automatically* if available

6. Disable Antivirus/Firewall

Windows Defender: Windows Security –> Virus and threat protection

Third-party software: Turn it off or uninstall it.

Re enable it after testing.

7. Use a VPN or Turn Off Your VPN

This is especially helpful if you think you might be IP banned.

  • Choose a VPN like HotspotShield or ExpressVPN
  • Connect to multiple servers in different regions and test them all
  • Test your Roblox again.
  • If you’re using a VPN turn it off and see if it works now

8. Reinstall Roblox

Windows:

  • Control Panel –> Uninstall a program
  • Select Roblox –> Uninstall
  • Download a new installer from Roblox.com

macOS:

  • Go to Applications folder
  • Drag Roblox to Trash
  • Empty Trash

9. Other Methods

1. Flush DNS Cache

Windows: Open Command Prompt as admin, type “ipconfig /flushdns”

macOS: Open Terminal, type “sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder”

2. Check Hosts File

Make sure no Roblox related entries are blocking the access

Windows: C:\Windows\System32\drivers\etc\hosts

macOS: /etc/hosts

10. Reset Internet Options (Windows)

Open Control Panel –> Internet Options –> Advanced tab –> Reset –> Reset all settings

1. Update Network Drivers

Windows: Device Manager –> Network adapters –> Update driver

Access router admin panel (192.168.0.1 or 192.168.1.1 in your browser address bar)

Look for any blocking rules or parental controls in Roblox

11. Roblox Server Side Problems
