    Check Your Internet Connection

    When you get the “err_internet_disconnected” error, the first thing to check is your internet connection. An inactive connection prevents your browsers from loading your sites, resulting in the above error.

    You can check your connection by using another web browser on your computer and opening a site. You can also use another device on the same connection to see if a site loads.

    If your internet connection has problems, reboot your router and see if that fixes the issue. You can try other internet troubleshooting methods or contact your internet service provider for help.

    2. Select Network & internet in the sidebar on the left.

    If your site loads after disabling the VPN, your VPN app is the culprit. In this case, either contact your VPN company for a resolution or get a new VPN app.
