Typical problems with the VPN:
- You cannot VPN into your network from your very own network (kinda duh)
- You cannot login two users simultaneously
- You cannot login to your network from another network with the exact same settings. You can probably reach your own HDA, but not other systems in the network, due to routing (the HDA has direct connection via the VPN tunnel).
- Check that you have port forwarded 1194 udp.

Moving to TCP
If UDP is not working because of a shitty ISP (see list below). Then you will have to change from tcp to udp and change your port forwarding of 1194/udp to 1194/tcp.
Client side: (Windows)
Right click the red A, click edit settings. If you have a thing saying "HomeHDA > " then mouse over it and click edit settings. Change:
proto udp
to
proto tcp
If for some reason the DDNS (yourhda.com) is not working but your control panel is updating, the add this line at the top of the config file.
remote YOUR_IP_HERE
Note: If you have a dynamic ip, then you will probably need to update this everyday. If you have a static ip then you are fine.
Manually (Windows)
Edit this file manually or use:
Seven x64
C:\Program Files (x86)\HDAConnect\config\HomeHDA.opvn
Seven x86 or 32 bit (Also most other Windows versions)
C:\Program Files\HDAConnect\config\HomeHDA.opvn
Run notepad as admin and open the above file.
Client Side (Linux/Mac)
Similarly, locate the configuration file and change
proto udp
to
proto tcp
On the Server side
Edit this file:
/etc/openvpn/amahi.conf
Command:
sudo gedit /etc/openvpn/amahi.conf
or
sudo nano -w /etc/openvpn/amahi.conf
change "proto udp" to "proto tcp"
Restart both sides and you are now using openvpn over tcp. And add your isp below.
List of bad ISPs
Please add your isp if you need this work-around:
- Bell Canada
Client reports "TLS handshake failed" & does not connect
This is usually caused by packet corruption that may happen for some users.
Follow the tutorial on "Prevent_SSL_Handshake_Timeouts_In_OpenVPN" page to fix this.
