sshd issue with logging in

Suddenly I can't logg in to server.

No idea, what are you expecting to happen? password authentication? key authentication? What does the server side log say? There's nothing "wrong" in there to help you with.

Did you change the permissions of your home folder (it mustn’t be writable by anyone but yourself) or the .ssh therein (it mustn’t be readable by anyone but yourself).
