I have a problem with openVPN.

My certificates can't connect.

In the log of the server, I got:

Authenticate/Decrypt packet error: packet HMAC authentication failed

Anyone know what the cause is ?

This usually means you have the wrong ta.key installed on Server or client.

Check

tls-auth /etc/openvpn/easy-rsa/pki/ta.key 0

or

<tls-crypt>

Make sure the are the same.
