AWS VPN No longer works

After upgrading to Fedora 34 from 32, my AWS VPN no longer works - either by using my Network manager or directly on the command line.
If I try and use openvpn, I get the following error:

alexlashford@localhost ~/Downloads> openvpn --config Alex.ovpn
2021-07-16 10:42:16 --cipher is not set. Previous OpenVPN version defaulted to BF-CBC as fallback when cipher negotiation failed in this case. If you need this fallback please add '--data-ciphers-fallback BF-CBC' to your configuration and/or add BF-CBC to --data-ciphers.

How do I debug this and fix it?

You can edit cipher in the advanced settings for your VPN connection.
Or better edit the server config to match cipher on the client.
