ssh Server unexpectedly closed network connection

i’m trying to connect to my digital ocean Ubuntu 16.04 server through ssh and sftp using putty and winscp. But i get the error “Server unexpectedly closed network connection”.

I do have access through the digital ocean control panel.

anyone knows what to do in a situation like this?

I had same problem. I did :

cd /etc/ssh chmod 400 *

What In don’t understand is why those files were with wrong chmod. ???

@soerenfrisk @jtittle But if you have access to console and you’re migrating to a new server, can’t you just run the scp commands in the console and then kill off the old server?

Hi @soerenfrisk Maybe you accidentally activated the firewall or have a too hard configuration of IPS like fail2ban? If you run this command in the console, what does it tell you?

sudo ufw status numbered
