VPN blocking in Russia

In this post, we have tried to answer the question: what is happening and who is to blame. Why does VPN work fine for some users, but not for others? Why has the same VPN service stopped working on the phone, but works without problems on the PC?

If you ever experience difficulties using Instagram through VPN connection in Russia, blame this man. You even to complaint to him directly like "Hey! I just paid my VPN subscription but it is not working at all! What the heck!"
