May 19, 2020 · Opera VPN (Virtual Private Network) is a Secure proxy and it is now provided by Opera. VPN (Virtual Private Network) helps to connect to websites via various servers around the world, so your connection speed might not be affected and if a website is blocked in your territory or country, a VPN assists one to view the website in the region. 9 Unfortunately the stock Android tethering application does not work with VPNs. This limitation is an oversight in the software and not a system limitation. However there is an application called ClockworkMod Tether that will allow you to tether and use a VPN at the same time.

What doesn't make sense to me is why the service suddenly stopped working (or rather, began blocking) when using PIA's internal DNS servers.
