Arch Linux - implementing OpenVPN Configuration scenarios to Authenticate with 'TLS scenarios: TLS handshake scenarios'
I've looked through the documentation and I'm still confused about Quick question that's been bugging me - I'm currently trying to set up an OpenVPN client on my Arch Linux system, but I'm running into an scenario where the connection fails with the behavior message: `TLS behavior: TLS handshake failed`... I've ensured that my configuration file is pointing to the correct server and that all necessary certificates are in place. Here's a snippet of my `client.ovpn` configuration: ```bash client dev tun proto udp remote vpn.example.com 1194 resolv-retry infinite nobind continue-key continue-tun remote-cert-tls server cipher AES-256-CBC auth SHA256 key-direction 1 <ca> -----BEGIN CERTIFICATE----- MIID...your_ca_certificate_here... -----END CERTIFICATE----- </ca> <cert> -----BEGIN CERTIFICATE----- MIID...your_client_certificate_here... -----END CERTIFICATE----- </cert> <key> -----BEGIN PRIVATE KEY----- MIIE...your_client_private_key_here... -----END PRIVATE KEY----- </key> ``` I've confirmed that both the CA certificate and client certificates are valid and not expired. Additionally, my network settings seem fine as I can ping the VPN server without any issues. I even tried using `--verbose` in the OpenVPN command to get more insights, but it just repeats the same TLS handshake behavior. I also checked the firewall settings to ensure that UDP traffic on port 1194 is allowed. Could this scenario be related to an incorrect cipher or perhaps a mismatch in the OpenVPN version between the client and server? Any suggestions on how I might troubleshoot or resolve this would be greatly appreciated! For context: I'm using Bash on Linux. This is happening in both development and production on Ubuntu 20.04. Any pointers in the right direction? This issue appeared after updating to Bash stable. Any advice would be much appreciated.
