Migration tool and root problems

[femotvaff]

Hi, I was using the Plesk migration tool to migrate some subscriptions from server 1 to server 2.

the migration was failure and after that if I try to connect with SSH root (putty) the connection is closed from server (same with other tools: closed by server exitcode 254)

what happened? any idea? :/
What I can try to do?

I can access plesk, but... what can I do from plesk ?

check firewall rules, status of sshd service at least.

I can't access with ssh (terminal/putty) is there a way to check/restart sshd service from plesk?


I tried to reboot server too. But nothing.

What I'm trying now is to start sshd by scheduling a task on plesk...

sshd in on, is not the problem.
even because I can insert user and password only if password is correct the connection is closed.

and firewall is not on my plesk 12
other ideas ? from plesk?

Thank you

SOLVED

the problem was in the file etc/security/limit.conf that I changed before last migration.

in rescue mode found checking
/log/secure
