I upgraded my Sophos Connect client to the latest version 2.3 ( Sophos Connect 2.3 Update Released) and since then cannot connect via SSL VPN to my UTM / SG230 obviously because of a cipher incompatibility.
Client says Timeout
openvpn.log says:
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.
I even cannot fix this because the UTM doesn't provide any of the ciphers listed behind "currently" as a cipher setting. I tried AES-256-CBC but this didn't help and instead created issues with all other users not being able to reconnect suddenly.
Any ideas?
Best regards,
