Hello,

I have a problem with connecting my client with my openvpn server.
got the error:
Authenticate/Decrypt packet error: packet HMAC authentication failed

It looks like there is problem with the key.

If you can post part of your server/client config
we can verify a little more.

I found the problem.
I sued the same key for server and client,
in the config of server and client (ta.key).

But the key was updated on the server,
and not in the client ovpn-file.

Put it in the ovpn-file,
send it to the client and it was ok.
