TLS Error
-
Hi all,
I have pfSense 2.4.3 with OpenVPN configured as both a Server and a Client. Both Server and Client are working correctly.
However I'm noting the following errors in the OpenVPN log:
Jun 5 08:28:40 openvpn 43102 TLS Error: cannot locate HMAC in incoming packet from [AF_INET]181.215.195.234:47099 Jun 5 07:20:04 openvpn 43102 TLS Error: cannot locate HMAC in incoming packet from [AF_INET]185.200.118.58:35062 Jun 4 18:50:53 openvpn 43102 TLS Error: cannot locate HMAC in incoming packet from [AF_INET]185.200.118.49:44359 Jun 4 07:03:22 openvpn 43102 TLS Error: cannot locate HMAC in incoming packet from [AF_INET]185.200.118.72:35633 Jun 3 18:49:25 openvpn 43102 TLS Error: cannot locate HMAC in incoming packet from [AF_INET]185.200.118.50:44700 Jun 3 16:37:29 openvpn 5256 Initialization Sequence Completed
I don't know what is causing the error or whether it is client or server related.
Comments appreciated.
TIA
Greg
Edit: There is no connection to the Server at present.

Usually that means that some other client (not OpenVPN) hit the port. It might be a port scan, a monitoring probe, or a client that doesn't have the right TLS key for example.

I think you are correct, as I just did a port scan, using one of the online tools, on port 1194 and the error appeared. Seems to confirm your thoughts.
Thanks.
