HI,
I have the same problem, in my case I receive the error message below on openvpn clients, but this only occurs on computers running Windows 11, on computers with Windows 10 it connects normally without error.
If you could help me I would be very grateful.
Below is the error message that occurs on Windows 11 computers:
OPTIONS ERROR: failed to negotiate cipher with server. Add the server's cipher ('AES-128-CBC') to --data-ciphers (currently 'AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305') if you want to connect to this server.
Below is an excerpt from the configuration file that mentions the "ciphers" settings on clients.
# Select a cryptographic cipher.
# If the cipher option is used on the server
# then you must also specify it here.
;cipher x
cipher AES-128-CBC
auth SHA256
If it is still relevant to you, or in case if someone else will search for the same answer - here:
replace cipher AES-128-CBC
with --data-ciphers cipher AES-128-CBC
I think it's a version mismatch...
