When I try to play the game ''Garry's mod'' , my connection closes, this results to me not being able to use any internet services like google chrome and Discord. I did not have this problem when I bought the VPN, it started doing this randomly.
Could you try to disable tracking protection and browsing protection?Note that in some cases game servers might block any connection coming from VPNs or proxys.
Using a VPN, your connection will be encrypted allowing to safe gaming process. This is the way to route all your Internet traffic through VPN and do not worry about its safety, because all information that can leak will be encrypted and get incomprehensible for hackers. I use paid VPN service, Nova VPN. For now I have no problem with speed 'cause it not violate Internet connection speed results.
