n2024 no ssh password prompt

Hello,

I'm trying to access to my switch using SSH. The ssh server is up and running, but cannot connect to it. The ssh connection starts, but get stuck, without providing the password prompt.

I've tried many configurations, without success.

Here is my last configuration, any advice?

username "admin" password xxxxxxxxxxxx privilege 15 encrypted
aaa authentication login "localmethod" local
line ssh
login authentication localmethod
exit
ip ssh server
ip ssh protocol 2

DSA and RSA keys have been already generated.

I have the issue on 2 different devices, runnning firmware 6.3.0.9.

Thanks!
