Interesting, I get the "IP address blocked by admin" message when I turn ON a VPN. I have tried two VPNs and get the same. Doesn't matter on my phone or PC. Everything works fine for me without a VPN.
Be careful as to where you assign the VPN. I would not recommend International cities, but go for domestic...
Everything works fine for me without a VPN also.... but then the IP address is known.... every where you go...
