Check the assets

If you’re getting this error while accessing an asset on Roblox, it’s quite possible that the said asset is either corrupted or modified.

Reset host files

If you’re facing the Roblox error code 403 on Windows 10, you can also try resetting host files back to default following the steps below.

  • Open Notepad on your PC.
  • Copy the following text and paste it into the text file.
# Copyright (c) 1993-2006 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # # source server # # x client host # localhost name resolution is handle within DNS itself. # localhost # ::1 localhost
  • Save the file text file as hosts.
  • Search for %WinDir%\System32\Drivers\Etc and open the folder.

Disable antivirus

Overly aggressive third-party antivirus or antimalware programs can sometimes cause problems. In such cases, try temporarily disabling your antivirus to see if that makes a change.

Disable VPN

Geo-restrictions often get in the way of software experiences. If you’re playing Roblox with a VPN connection, chances are the VPN itself is interfering with Roblox’s update system, and there’s a region conflict in which your IP address is placed due to the VPN and the update Roblox is sending you. Try disabling the VPN to see if Roblox works.

Check Firewall

Sometimes the Windows Firewall can get in the way of programs trying to access the internet, which can very well be the case here. Try temporarily disabling your firewall to see if Roblox starts working properly.
