You can also follow @Roblox on Twitter to stay updated on scheduled and ongoing maintenance. You can do this via a free server status detector. If the server is down, you can do nothing but wait.
3] Logout and re-login
One of the many reasons why Roblox cannot allow you entry is corrupted login cookies. But this is a situation where logging out of the Roblox player, and then logging in may resolve this issue. As you do so, the app recreates new cookies, replacing all the corrupted ones.
4] Clear Roblox Cache Data.
The Roblox cache data can also be why the Roblox Error Code 403 occurs. Roblox stores cache data to allow faster access and enhance user experience. However, an unexpected system crash or malware attack can corrupt the cache folder. Here’s how to clear the Roblox cache Data:

- Restart your device and see if the error’s fixed.
5] Temporarily Disable Firewall or Security Software
Antivirus software and Windows Defender Firewall can sometimes interrupt applications and their processes.
You may disable the antivirus temporarily, and if that does work, allow Roblox through the firewall. Disabling both can help fix the Roblox Error Code 403.
6] Modify DNS Settings
As Error Code 403 in Roblox could be a server-related error, switching to Google DNS can help fix it. Here’s how:
- Click Win + R to open the Run dialog box.
- Type ncpa.cpl to open the Network Connections window, and click the OK button.
- Right-click on the current network and select the Properties option.
- Click on the Internet Protocol Version 4 (TCP/IPv4) option and then on the Properties button.
- Next, select the Use the following DNS server addresses option.
- Type the addresses mentioned below in the corresponding fields:
Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4
- Go back to the previous window, click on Internet Protocol Version 6 (TCP/IPV6), and then on the Properties button.
- At last, select the Use the following DNS server addresses option and enter the following addresses:
Preferred DNS server: 2001:4860:4860::8888

If you use a 3rd-party VPN software, right-click on its Taskbar icon and select Exit.

- Press Windows + I to open Settings.
