Could not connect to AirVPN by any means

[wasteemail 0]

Hi,

Yesterday i subscribed for a 3 day AIRVPN plan. I installed "openvpn-install-2.3.4-I002-x86_64.exe" and generated config files with USA and UK servers having ports TCP 443 alone. Everytime i try connecting it gives a TLS handshake error. My PC is connected to our organisation's firewall, Fortiguard which filters our Internet connection. It has only port 80(TCP) and 443(TCP) opened [ checked it through Nmap tool ]. All other ports are closed. OS- windows 7 64 bit. Here is my log,

and this repeats..

What i found out is, i opened Ultrasurf Proxy [which is the only proxy software that works bypassing Fortiguard in my organisation] and connected to its proxy and then tried connecting AirVPN and voila, it got connected without an problem to an USA server. After i disconnected Ultrasurf, AirVPN couldn't connect back. !!! I also installed Eddie 2.6 and tried connecting with "protocol TCP 443" selected from preferences, but couldn't connect. I even tried SSL 443 but couldn't connect here is my log,

I did raise a support ticket and their reply was,

 

There is no communication between your node and the VPN servers.

You are maybe behind a proxy. If so, OpenVPN can connect over a proxy. You need to know proxy type, proxy listening port and IP address (or reachable host name), authentication type (if any), authentication credentials (if any). Then you can generate a configuration file with such parameters (tick "Advanced Mode" in the Configuration Generator and fill in the proxy parameters).

If you think you are not behind a proxy, try a connection of OpenVPN over SSL. In our client Eddie you can quickly test OpenVPN over SSL by clicking "AirVPN" button, selecting "Preferences", clicking "Protocols" tab,  selecting "SSL Tunnel - Port 443" and clicking "Save". Eddie supports OpenVPN connections  over a proxy as well (they can be configured in the "Proxy" tab).

Kind regards

But i would like to point out that, i could communicate with AirVPN servers when using Ultrasurf and my internet connection dowsn't go through a proxy.

 

Kindly can anyone help me out.

Hello!

 

Since Ultrasurf employs HTTP proxies, probably your company Fortigate firewall allows those packets. Additionally, your solution (OpenVPN over Ultrasurf if we understand it correctly) is quite elegant. There is widespread concern about Ultrasurf, the addition of a further OpenVPN tunnel potentially solves any risk, because data are still encrypted by OpenVPN when they pass through Ultrasurf servers. See for example https://en.wikipedia.org/wiki/Ultrasurf#Evaluation in particular Appelbaum's concerns and criticism.

 

Kind regards

Hello,

Is there anyway where AirVPN can work. This is the only VPN whose website is not blocked by our company [meaning without any proxy i could directly load up your airvpn page whereas other VPN websites get blocked under proxy avoidance category] but it's software whether be it openvpn or eddie gets blocked from communicating to your servers.

Ask your network admin to allow OpenVPN through. (Yes, I realize that might not be an option.)

 

It might be possible to circumvent the firewall, but if your network people are competent then I would expect Air's servers to be blocked soon enough anyway when they see what is going on.

Yes the first option is not really going to work. Regarding your second option, if it might be possible to circumvent the firewall, then do enlighten me. Our network team dont do any deep packet inspection or analyze data 24X7. From a base of what has been provided by Fortiguard firewall, they add up sites to their filter when they come to know of it mostly through rumours or chit-chats circulating inside our organisation. And even if they block airvpn servers after a certain period of time,say 6 months, given that time i would say it is more than enough for me. Alas, let me give a try.
