OpenVPN TLS Handshake Failed

zkern5254 · 1 Jun 2023, 15:34

I'm trying to run OpenVPN and it seems like it can't establish the TCP connection for the tunnel.

I'm getting the follow output from OpenVPN:

Not sure what is the most important line here but the TLS handshake failed might be something.

I did create a device on the OpenVPN portal and exported the .opvn file. Then I ran:

openvpn --script-security 2 --config mykeys.ovpn

(did it not a daemon to see the outputs)

The drone is connected to over wlan0 and I can confirm network connection with a successful ping of google.com

Thanks in advance for any help.

To all that might come across this, updating to OpenVPN 2.4.6 solved this issue. Note that a reset of the VOXL is required before the upgrade will take hold.

Also, if you are using the vpn-start service, do not use the full file path that is there by default; instead just use the openvpn call like you would in a terminal and use the file path to sudo /usr/bin/sudo before the openvpn call like this:

/usr/bin/sudo openvpn --daemon --script-security 2 --config mykeys.ovpn

If you don't make this change, it will try to run the older version of openVPN and will run into all kinds of issues.
