Attempt the following before reaching out to your VPN provider for further support:

  1. Start the VPN. Ensure it is connected BEFORE doing anything else.
  2. Now tap Settings > Network & Internet > VPN
  3. Tap the Settings Icon of your VPN (the little gear to the right of the name of the VPN).
  4. Tap Always-on VPN.
  5. Tap the Block connections without VPN.
  6. Sometimes this restarts the VPN. If it doesn't, turn it off manually.
  7. Restart the VPN. If it hangs (like mine sometimes does) choose another temporary region. 99% this clears the initially stall/disconnect form the Internet
  8. Reconnect to your region of choice.
  9. Verify DNS leaks by testing at dnsleaktest.com
