openssh - SSH: Connection closed by remote server -


i trying ssh login remote server. whenever try login through terminal using ssh command:

  ssh root@{ip_address}

i error:

 connection closed {ip_address}

i checked hosts deny , hosts allow, there nothing in file. not getting why happening?

it happened when changed workstation , key got changed. when tried ssh login, asked add key , entered yes , closed connection.

is there way connected ssh again?

your appreciated.

thank you.

edit:

output of ssh -v -v -v -v root@{ip_address}

are sure server permitting root logins via ssh? if not, suggest using different account sudo privileges instead of enabling root login - if server's ssh port accessible whole inernet.
