I keep getting this error: The remote connection was not made because the attempted VPN tunnels failed. The VPN server might be unreachable. If this connection is attempting to use an L2TP/IPsec tunnel, the security parameters required for IPsec negotiation might not be configured properly. Anyone that knows why?

Do you have a firewall on your droplet?

Geekologist December 2, 2013

No, I don't think so.

can I check that somehow?

Have you tried rebooting your droplet, i.e. sudo reboot now?

In installing your VPN server, did you follow a guide? If so, which one?

Geekologist December 2, 2013

Yes, I have tried to reboot it.
I followed this one: https://www.digitalocean.com/community/articles/how-to-setup-your-own-vpn-with-pptp

How To Setup Your Own VPN With PPTP

by Bulat Khamitov

A Point-To-Point Tunneling Protocol (PPTP) allows you to implement your own VPN very quickly, and is compatible with most mobile devices. Even though PPTP is less secure than OpenVPN, it is faster and uses less CPU resources.

"... I only isntalled the server part, as it is my home windows machine that I am trying to connect"

You have to do the equivalent of Step 5 - Setup Clients, from the tutorial, on your local machine.

I am using Windows's inbuild VPN program, which supports PPTP.
