forticlient in ubuntu 22.04.1 LTS, the prompt for fortitoken disappear immediately

Can you try below setting on Fortigate?

config system global

set remoteauthtimeout 30

end

Hi Hoygen

On your FortiGate, do you have multiple RADIUS server configurations?

If so, on possible reason is that the FortiGate sends the authentication request to all available RADIUS servers and the first received response (from any RADIUS server) will be accepted by the FortiGate.

Hello, and thank you for your answers. I do not have access to the fortigate, the fortigate is handled by the customer. I think it is an issue of the forticlient in ubuntu.

I received another fortitoken for another customer and the behaviour of the application is the same. The request to insert the fortitoken code just disappears in a second.
