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
scpcommands 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?
