Hello,

I am receiving a lot of TLS ERROR, comming from the same source IP:

Mar 27 09:46:49 VPNie1 openvpn[11843]: TLS Error: cannot locate HMAC in incoming packet from 88.72.13.189:32871
Mar 27 09:46:53 VPNie1 openvpn[11843]: TLS Error: cannot locate HMAC in incoming packet from 88.72.13.189:32871
Mar 27 09:46:55 VPNie1 openvpn[11843]: TLS Error: cannot locate HMAC in incoming packet from 88.72.13.189:32871
Mar 27 09:46:56 VPNie1 openvpn[11843]: TLS Error: cannot locate HMAC in incoming packet from 88.72.13.189:32871

I am wondering if there is a way to debug or track the user which try
to connect to the service, probably with an old certificate.

Thanks for you advice
doesn't look like an old cert but somebody who's trying to connect
without the proper 'tls-auth' key...

HTH,

JJK
