Devops & sysadmins: fix ‘tls error: tls handshake failed
I’m not sure if the port is available or not. Using nmap, I discovered that the port is “filtered.” The C7 is protected by an ISP’s router, which forwards all ports to it (So I can use the proprietary VoIP landline).

Openvpn – tls error: tls key negotiation failed to occur
I recall having similar/identical issues when attempting to set up via portmapper.

Finally, I stopped monitoring this issue because I just wanted to set it up as a fallback if IPv6 was not available on the client’s site.
Fix tls key negotiation failure issue with proxy.sh openvpn
The VPN server worked fine when I connected via another WAN interface that was reachable via IPv4, so I believe the portmapper is the problem.
Openvpn with tls and user authentication on pfsense part1
Is there something that suggests you shouldn’t set up your server for IPv6?
Openvpn tls error: tls key negotiation failed
With a reachable IPv6 on your WAN, a portmapper can only be used for clients who do not support IPv6 (it just does not support udp)

First and foremost, I previously used a pfsense in the same environment and it worked perfectly.

Second, I have an openvpn server in my network that works great (but that server does not have a webgui to handle the vpn, and I no longer want to open ports, which is why I want to use the vpn on the opensense), and I have to use the portmapper because cellphones do not support IPv6 (at least in germany).
SOLVED: It’s an odd solution, but at least it’s a solution.
The firewall rule was ipv4+ipv6 ond wan adress (as set by openvpn), so I changed it to ipv6 on WAN adress (which didn’t work), then changed WAN adress to single hosten and placed in the ipv6/128 and it worked!
I changed it back to a WAN address after that and it still works.
I had a similar problem when I opened a port to a network machine and the alias didn’t work but the IP did.
Now I’ve changed the rule back to alias as well, and it now works.
Perhaps there is a problem with the aliases.
Openvpn issue – tls key negotiation failed to occur within 60
To encrypt SMB traffic over the public Internet, I’m using OpenVPN 2.3.6-1 on my Arch Linux server. I get the following error when I test the configuration on one of my Linux virtual machine clients: Error with TLS: The TLS handshake was unsuccessful.
To set up OpenVPN, I followed the instructions at (https://wiki.archlinux.org/index.php/OpenVPN) and to generate the keys and certificates, I followed the instructions at (https://wiki.archlinux.org/index.php/Create a Public Key Infrastructure Using the easy-rsa Scripts). The only changes I’ve made to these instructions are the names of my own machines and the names of the key/certificate files that correspond to them.

It was a problem with the port forwarding rule I built on my gateway, as suggested by Michael Hampton and Michal Sokolowski in the comments on my question. OpenVPN is set to use UDP, and I forgot to switch the gateway from TCP to UDP because I seldom use that protocol. My VPN is now operational since the forwarding rule now uses UDP.
Hardening openvpn with tls authentication
This error occurs when one side has the tls-auth option activated but the other does not. You should check whether the directives are active or inactive in the configuration files on the server and client; in both cases, the directive must be set equal.
Yes, the ‘–key-path’ directive in client.ovpn is an alternate way of defining the direction parameter for –tls-auth –> https://community.openvpn.net/openvpn/wiki/Openvpn24ManPage, however the server.conf, as far as I can tell, is missing this directive.
