Bug description:
  Latest network-manager-openvpn still uses the deprecated --cipher
  option, and offers no way to set the new --data-ciphers option.

  nm-openvpn[257279]: OPTIONS ERROR: failed to negotiate cipher with server.  Add the server's cipher ('AES-256-CBC') to --data-ciphers (currently 'AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305') if you want to connect to this server.
  nm-openvpn[257279]: ERROR: Failed to apply push options
  nm-openvpn[257279]: Failed to open tun/tap interface

  Using the command line and passing --data-ciphers option works.
