Can't create client anymore

[T0MuX]

Hi,

I suddenly couldn't create client anymore with this script on my VPS. After a bit of investigation, I decided to restart all from scratch. Chosen Debian 12 (previously Debian 11). Full updated. Then, downloaded your script again to setup OpenVPN Server. And, sadly, I get exactly the same issue : it can't create a new VPN client. I let you read the stdout below. As you can see, even if it says "Client t0mux-pc added." this is not true. If I run again the script to revoke an existing client, it says there is no client.

Tell me a name for the client.
The name must consist of alphanumeric character. It may also include an underscore or a dash.
Client name: t0mux-pc

Do you want to protect the configuration file with a password?
(e.g. encrypt the private key with a password)
   1) Add a passwordless client
   2) Use a password for the client
Select an option [1-2]: 2
