As your own log says:
DEPRECATED OPTION: --cipher set to 'AES-256-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-256-CBC' to --data-ciphers or change --cipher 'AES-256-CBC' to --data-ciphers-fallback 'AES-256-CBC' to silence this warning.

You need to add this to your .ovpn file:

cipher AES-256-CBC
data-ciphers AES-256-GCM:AES-128-GCM:AES-256-CBC
