Why am I getting an access denied message?
The Access Denied error can occur in different instances. Sometimes specific, and other times just generic. However, in most cases, it usually has to do with permissions. In a typical scenario, the error appears when your browser uses different proxy settings or VPN instead of what’s set on your Windows 11/10 PC. Thus, when a website detects that there is something wrong with your browser cookies or your network, it blocks you and you won’t be able to access the website.
