Re: [gentoo-user] OpenVPN - error

[Roger Welsh]

Hi Thelma,

I think you need 
tls-server 
And 
tls-client 
In your respective configs below.

Reference:
https://askubuntu.com/questions/594868/openvpn-hmac-authentication-failure-no-matter-what-i-do

And
https://openvpn.net/community-resources/reference-manual-for-openvpn-2-4/ 
Grep for tls-server.
