I had LiquidVPN service for years, it worked like a charm. Not it doesn't work anymore from any of my PCs, the app for Android doesn't work anymore and it has disappeared from Google Play Store. I logged in to the client area and I wrote support ticked and it is almost 2 months I am waiting for answers. My opinion: looks like the service is no longer active.
Good to start with but the openvpn connections no longer work from any of my PCs or connections. L2TP does, but that's not what i need. Support has responded only once in 4 days to say "sorry for the delay." Moving on from this supplier.
liquid vpn is faster than all of the other services I have ever tried. Its a shame they do not add locations as fast as some of the more popular ones but I guess they must spend less on advertising.
