VPN connection does not connect on my IPhone(13 pro) in the OpenVPN app, infinite download followed by an error. I use connection type TCP-443,53,80 ; does not connect. What should I do? 
*I live in Russia, using a Wi-Fi network*

Same problem today (phone and pc through WireGuard).

Yes, direct OpenVPN, Wireguard and even Tor is now blocked at the TLS handshake stage, because any traffic containing no recognizable data is now rejected by default (just like in China).

Currently this may be circumvented by using SSH or SSL wrapping. More on how to set up an SSH tunnel is here, and the same about SSL is here.

The method is this: you first start an SSL or an SSH client in proxy mode, it connects to a remote AirVPN server, then you start a normal OpenVPN client but specifying it to connect to 127.0.0.1:proxy_port instead of a remote AirVPN server. All the needed settings are already in the config files generated by the Config Generator.

The connection will still be slow and possibly unreliable. I guess DPI is trying to analyze all traffic going to the foreign servers (besides YouTube, Google, etc.) and throttles it if some statistical patterns are detected.

The solution for Tor is to use a webtunnel bridge - those were recently implemented and use the same "fake HTTPS traffic" approach.

Reinstalled all of the tunnels, updated all of the configs. Using UPD Oceania to port 443. It started working yay around 9 pm. Also had luck to connect for an hr during the day. PC.
My phone still doesn't connect. Yet connects via wireguard to wrap (lol).  But I think I will just uninstall openvpn and other tunnels on it and update configs as well.
My cofigs were also old, I was getting error message, that open vpn will stop supporting it soon.
Thanks for this thread, awesome to see that you are not alone :)

Starting today (Saturday) we have the same issue in Belarus...
iOS: German server works via WG using cellular network (it seems A1 carrier doesn't work with any server/connection)
PC/Mac: OpenVPN over SSL works as well as OpenVPN over TOR. Vanilla WireGuard and OpenVPN don't work for ip addresses outside country. Local WG home-to-home works for now.

please fix config generator for SSL ipv6 connection
1.

remote 127.0.0.1 1413
is not a valid ipv6 address
2.
route 2a02:4840:2:226:5704:5836:cab9:e03b 255.255.255.255 net_gateway
also needs to be fixed.

У кого так же, как у меня перестал подключаться впн, поменяйте протокол, я потыкал и вот через эти впн снова заработал. Надеюсь кому то помог. 


Smart boy, but what about 100x speed decreasing?

______

There are still live servers on UDP and wireguard, I don’t want to write about them in case they are watching.
The most interesting thing is that if the handshaking has already passed, then connect works without any problems 100M in - 100M out, I have one live session to an already banned server for 1 week. Somehow we need to figure out how to switch from the encrypted SSH to the UDP seamlessly, or just buy some proxies for bitcoins

What about android AirVPN app? I can't find any settings related to SSH/SSL protocol here

I just came upon this thread. I think there should be a proper updated guide from the staff or someone who has been able to setup TCP over SSH without the eddie client on windows/linux/mac/android.

The android version of eddie doesn't supports TCP over SSH as well as the guide for doing it manually on android did not work for me.

I have managed to use that thing on my very restrictive corporate/work wifi network and it was working. If you have it connected your windows device via Ethernet it will be better. but wifi will work as usual.

Windows:

Step 1 : Select the TCP over SSH connection in eddie UI client on windows and connect and under network lock allow DHCP,if you use network lock

Step 2: Go to mobile hotspot option on windows network and internet and turn it on.

Step 3: Go to network connections.
           You should see a new local area connection* and you will see Microsoft wifi direct virtual adapter under it.
           You will also see a network adapter named - Eddie Tunnel

Step 4: Open eddie tunnel properties (right click on it) and goto the sharing tab

Step 5: select the option - Allow other network users to connect through the computer's internet connection. (It will show a message that its being used by the wireless network, ignore it)

Step 6: select the local area connection * option and click ok


Now when you are connected to the wifi hotspot (that is created in the second step) of your PC/laptop you are connected to the VPN on any of your devices.
The few problems you will face it. Possible DHCP attacks if you dont own the router , Hotspot will fail to connect sometimes and if your connection drops you will have to remove your router wifi password from your android/ios device and turn off mobile data so in case if windows mess up and shuts down the hotspot due to some reason you will not leak data.

I know this is a very lengthy method and it will be slow as well but thats the only way I could find RN.

Now when you are connected to the wifi hotspot (that is created in the second step) of your PC/laptop you are connected to the VPN on any of your devices.
The few problems you will face it. Possible DHCP attacks if you dont own the router , Hotspot will fail to connect sometimes and if your connection drops you will have to remove your router wifi password from your android/ios device and turn off mobile data so in case if windows mess up and shuts down the hotspot due to some reason you will not leak data.

I know this is a very lengthy method and it will be slow as well but thats the only way I could find RN. 

 
thank you. It's a very good option for those who aren't lazy.

Hello!

Here the problem looks different, please see here to resolve this issue and test again:

Kind regards

Yeah, thank you. My issue was not related to ISP but Eddie-UI. But simple relogin not fully helps - I got another issue with TAP, so reinstalled with reboot. After that SSH->TCP works smoothly

Since about 3 days ago, when connecting via SSL tunnel manually (not using Eddie), I am getting the "Peer certificate required" error for almost all servers in the world. SSH tunnel works fine. I am using configuration files generated by the AirVPN Config Generator with all IPs pre-resolved and certificates/keys in separate files.

I am using my own script and a systemd service for automatic rotation of servers to make the connections look a bit more like normal connections, to prevent possible blacklisting (in case such a thing already exists).

If it's not an AirVPN problem, to me it looks like the sign of an attempted certificate substitution. In my script the stunnel daemon is started without any custom options, just by supplying the generated .ssl file.

Here is the log.
