  1. Thank you this helped. I’d like to add that for Step 6 on iOS, you can disable VPN by going in to General > VPN & Device Management > VPN > Status: off

  2. I tried every thing but nothing any positive happening for our website safari and Firefox refused to open our website but on chrome it opened. what the main issue i didn’t understand what’s going on to our website.

  3. macOS: Open Safari and click Safari > Preferences > Privacy and then click the Manage Website Data button and click Remove.

    More accurately, the item disappears and then quickly reappears. The same happens when I click remove all items.

    When I open a private window, the same thing happens.
