That such people, excuse my bad English, is not my native language.
To the topic:
I think they are blocking the service in Venezuela used the Internet service of the State company CANTV, simply the desktop application does not allow me to connect to any server of my free plan (note N/A on all servers including the free in The following image).
Without being connected to another VPN
Intrigued with this matter I wanted to consult the status of the service by accessing the page winscribre.com/status and also not load.
Without being connected to another VPN
To get out of doubt install ProtonVPN and this works without problem, even connected to proton the application of windscribe back to work and the same goes with the status page of winscribe.
It should be mentioned that the CANTV Internet provider Company has been applying blocking methods similar to those used in China and Russia.
I hope the Windscribe team can verify what I’m putting here.
