Fixing OpenVPN "Authenticate/Decrypt packet error: cipher final failed"
When connecting to a VPN I was constant getting the error Mar 8 09:29:27 openvpn[1696]: Authenticate/Decrypt packet error: cipher final failed I had imported the supplied ovpn file and had followed all the other configuration steps, so this was quite frustrating. Then I saw this in the logs: Mar 8 09:31:07 openvpn[1790]: WARNING: 'cipher' is used inconsistently, local='cipher BF-CBC', remote='cipher AES-256-CBC' Changing my client to use "cipher AES-256-CBC" instead of the default (which apparently was cipher BF-CBC) fixed the issue.
