I am trying to use OpenVPN to access the Protonvpn servers and following their instructions here https://protonvpn.com/support/openvpn-windows-setup/ to set it up.
Protonvpn works on my machine by itself fine, but OpenVPN is giving me the following error in the logs with any ProtonVPN server config for UDP or TCP configured:
2023-02-05 16:57:36 DEPRECATED OPTION: --cipher set to 'AES-256-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). OpenVPN ignores --cipher for cipher negotiations.

My hunch is that it is trying to read the wrong network adaptor but not sure how to figure out which one it is trying to look at, or how to fix it.
My network adaptors include the following in order of listing on windows:
Realtek ethernet, Virtual hostbox ethernet, TAP-ProtonVPN, TAP-OpenVPN, VMWare Network adaptor VMNet1, VMWare Network adaptorVMNet8.
Any advice how to address this would be of great help.
