Roblox has become this awesome online gaming platform where players can create their own games and have a blast playing them. However, users sometimes see the error code 403 when trying to log in or play. This 403 error means access to certain pages or files on the Roblox site is forbidden. It usually happens due to many issues with your internet, antivirus software, or outdated browser.

Common Causes of Error Code 403
