I need to urgently regenerate / renew the TLS AUTH and CA keys

[Studyhaxxx]

The config file I have to import into the clients, contains a certificate and a private key. A "ca" section and a "tls auth" section

Whenever I regenerate the OpenVPN Server - running on Synology NAS - settings,, the "ca" and the "tls auth" sections remain the same

I have tried to ssh into the NAS and grab the keys via admin, but when I ssh'd into it as root, I correctly entered the root passwords (same as admin in my case) and yet I got permission denied 3x and had to manually unblock myself from the firewall on the NAS. If I grab the entire openvpn folder's content as admin via SSH, I can NOT get / download the "keys" subfolder's content, only the "CA" section's content. "Server.key", "ts.key" and one other key "ts.cert" are NOT downloadable if I use the admin account.

Can someone help me solve this
