Hello how to fix this my cipher cipher AES-256-CBC its now working on my openvpn 2.5 client.. then i tried to change into cipher AES-256-GCM then it’s the same…
note: i only change in server.conf and base.conf the cipher.

this is the result: hu Aug 19 08:29:03 2021 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.
