It's most likely the hardware firewall within your router at home that's blocking the VPN connection if you've never been able to get it to work at home yet it works in other people's homes.

I read this elsewhere in relation to the same problem with the same error (credits to Robert Lin):

"check the router settings and make sure TCP Port 1723, IP Protocol 47 (GRE) are opened. Also make sure that the router has the PPTP enabled and not firewall block the traffic."
