I have one (1) premium account with AirVPN. On my work computer, I have set up an AirVPN connection by choosing servers from the Europe continent. A VPN connection is established and working well. Back at home, I have attempted to set up another VPN connection by choosing servers from the America continent. However, as I try to connect, Tunnelblick returns an error message "Authentication failed. The credentials (passphrase or username/password) were not accepted by the remote VPN server." If I go to the Client Area on this website, in a yellow box it says "Last attempted connection failed 2m 13s ago. Reason: Already logged on 'Naos'" Does all this mean that one (1) premium account is permitted to establish only (1) VPN connection from one (1) computer/device at a time? Or, if multiple VPN connections are permissible, say from a Mac, another Mac, and an iPhone, how would I establish such multiple connections without running into an authentication error? Thank you.
