Not able to open any machine IP

I am not able to open any machine active or retired. i have setup my terminal using openvpn name.ovpn but the ip’s are not doing what its supposed to do. i am new here so if anyone can help will be very nice. and for the record i am trying to open the opiimum (10.10.10.8). i have tried a few as well but same problem with every IP.
