[SOLVED] OPNsense 26.1 openvpn client instance TLS static key = TLS auth only absent

OPNsense 26.1.5-amd64 openvpn client instance VPN: OpenVPN: Instances TLS static key = TLS auth only, is absent from UI

This breaks my NordVPN connections, with error of TLS handshake failure, as below

TLS Error: TLS handshake failed

The option, TLS static key = TLS auth only, is required for NordVPN connection to authenticate and get the tunnel UP

OPNsense 25.7.11_9-amd has the TLS static key = TLS auth only, and NordVPN tunnels come up just fine.

Seems like an oversight / bug to me...

When will it be fixed ?
OPNsense 25.7.11_9-amd64 running on ESXi 6.7 U2 VM, 4Gbytes RAM, 2 x vCPU
frr OSPF + eBGP, IDS, AdGuard Home, mDNS proxy, sftp-backup plugins. OpenVPN, limited kea DHCP server deployment.

You set the TLS key in the Static Keys tab.

Then go back to your instance and the key will be available to use.

Thank you, yes i forget that step, working now....
