if u use vouchers, check which protocol open ports are opened: tcp or udp. if tcp provide the free hosts(make a working payload) in the http/tcp headers, with the open port configured, then connect vpn.Pwede ba sa mga voucher?
for testing use Droidvpn
first tell which open ports u have, udp or tcpNot working sa Unifi ng Ubiquiti router with voucher
also tell which device u are using pc/android?
