First thought is that your ISP may be blocking ports. Have you checked logs on both client and server, as described in the troubleshooting section of the README?

The error maybe with hairpin NAT. I would look into your modem or even setup a internal DNS to fix this issue. Another way you can test hairpin NAT is by launching a web server and attempting to connect to it from inside your network then from your data. The data should connect but internal network will timeout.
