Raspberry Pi Connection Closed SSH

Question

I just bought a raspberry Pi 3. I am trying to start it, but first wrote connection refusedabout the ssh attempt. After I started raspi-configand turned on ssh, I now got it Connection closed by 192.168.0.31. When I look at the ports on this computer, it is 22/tcpopen (using nmap). What could be the problem?

Answer 1

I found this solution, now ssh works:

sudo rm /etc/ssh/ssh_host_*
sudo dpkg-reconfigure openssh-server
