hi all,
whilst testing some new hardware with OpenVPN I ran into the following messages
which keep popping up from time to time:
AEAD Decrypt error: cipher final failed
Config:
server running OpenVPN 2.4.3, basic config, Ubuntu 17, kernel 4.14, openssl
1.0.2g
client running OpenVPN 2.4.4, basic config, CentOS 7.4, kernel 3.10, openssl
1.0.2k
it's the client that is throwing the above message during heavy load (900 Mbps VPN traffic). It happens only with NCP ciphers ,
I am not seeing any cipher messages with 'ncp-disable' set.
as soon as I add 'verb 5' or higher, the message goes away, because performance
drops to below 500 Mbps due to excessive output.
Any idea how to tackle this?
TIA,
JJK
