Hello friends, 

 

Impossible to get Open VPN to work. I use an ER7206 controller and Omada NAS version.

 

It worked before, but... a big mystery. Whether on Tel or PC.

 

On the log I get a recoverer for the logs:

 

Thu Sep 12 15:15:21 2024 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') if you want to connect to this server.
Thu Sep 12 15:15:21 2024 ERROR: Failed to apply push options
Thu Sep 12 15:15:21 2024 Failed to open tun/tap interface

 

On the phone I managed to connect at times but without passing data, I deleted the VPN several times and everything started again at 0 and the same.

 

Do you have any information?

 

 @Clive_A Yesterday you managed to save me, maybe you can too Xd

 

ER 7206 en V2.1.2

Omada controller V 5.14.26.1

 

Nice day from France

Maybe it has something to do with this
